THEORY

In this chapter we will discuss all the questions based on number series. In this type of questions candidate have to follow a definite pattern throughout the series. The task for the candidate is to follow the pattern and to complete the given series with the best alternative or to find the wrong term in the series.

DIFFERENT PATTERNS OF NUMBER SERIES

Pattern 1: When the difference between the consecutive numbers is same/ constant or the number series is in arithmetic progression.a, a + d, a + 2d, a + 3d, a + 4d, ........, a + (n – 1)d. Where a is first term, d is the common difference

Ex 1: 24, 21, 18, ?, 12, 9.

Where the difference is -3, answer is 15

Pattern 2: Any constant number is added to the difference of the consecutive numbers and form a series.

Ex 2: 2, 4, 8, 14, 22, 30

Next No. is 32 as 2 4 8 14 22 32

2 (2+2) (4+2) (6+2) (8+2)

Ex 3: 3, 4, 6, 9, 13, 18, __, Answer is 24 because 3 4 6 9 13 18 24

1 2 3 4 5 6Pattern 3: Multiplication or division Pattern

When a series is multiplied or divide by certain constant.

Ex 4: 6174, 882, 126, ?. Answer is 18, the series is divisible by 7.

Ex 5: 1, 2, 3, 6, 9, 18, ?, 54 (a) 18 (b) 27 (c) 36 (d) 81 (e) None of these

2 Number Series Completion

Solution: The given series is in the pattern × 2, × 3/2, × 2, × 3/2, ×2,.....

So, the missing term is 18 × 3/2 = 27 Or

1 2 3 6 9 18 ? 54

+1 +1

1

+3 +3

1 × 3

+9 +9

3 × 3

+27

9 × 3

Ans: (b) 27

Pattern 4: When a series follows the following pattern add, multiply, add, multiply, add,.... or add, substract, add, substract, add,.... etc.

Ex 6: 4, 6, 12, 14, 28, 30, .....

Solution: 4 6 12 14 28 30 60

+2 ×2 +2 ×2 +2 ×2

60 is the next number

Ex 7: 8, 28, 116, 584, ? (R.R.B 2002) (a) 1752 (b) 3502 (c) 3504 (d) 3508 (e) None of these

Solution: The given series is in the pattern: × 3 + 4, × 4 + 4, × 5 + 4, ..... (8 × 3) + 4 = 28 (28 × 4) + 4 = 116 (116 × 5) + 4 = 584 (584 × 6) + 4 = 3508So, the missing term is 584 × 6 + 4 = 3508.Ans: Option (d)

Ex 8: 3 4 10 33 136 685 ? (a) 3430 (b) 4802 (c) 5145 (d) 4116 (e) 5488

Solution: In this particular Series, the pattern is-

3 × 1 + 1 = 4; 4 × 2 + 2 = 10; 10 × 3 + 3 = 33; 33 × 4 + 4 = 136; 136 × 5 + 5 = 685; 685 × 6 + 6 = 4116.

Hence option (d)

Pattern 5: Series with Square or cube or square root or cube root of the number.

Ex 9: 1, 9, 25, 49, ?, 121 (S.S.C.) (a) 64 (b) 81 (c) 91 (d) 100 (e) None of these

Solution: The given series consists of squares of consecutive odd numbers i.e 12, 32, 52, 72,.....

So, the missing term = 92 = 81

Ans: Option (b)

Pattern 6: TRIANGULAR NUMBER

When any number series is in the form a, a + (a +1), a+ (a+1)+ (a+2), a + (a+1)+ (a+2) + (a+3), ........., nth term

of the series be ( ) ( ) + +=

n n 1 15 15 1

2 2.

Ex 10: 1, 3, 6, 4, 15, 21, ...... find the 15th term of the series?

Solution : 15th term = ( ) ( ) + +

=

n n 1 15 15 1

2 2 = 120 where n = 15.

3Number Series Completion

Pattern 7: Product of the digits and summation with any constant, gives next number of the series.

Ex 11: 69, 55, 26, 13, 5 [Find the Wrong term of the Series] (a) 69 (b) 55 (c) 26 (d) 13 (e) 5

Solution: We found that the series contains each term is one more than the product of the digits of the preceding term. Thus (6 × 9 ) + 1 = 55, (5 × 5) + 1 = 26, (2 × 6 ) + 1 = 13, (1 × 3) + 1 = 4. Hence option (e).

Pattern 8: Difference Between the adjacent numbers increases by a constant number.

Ex 12: 2, 7, 17, 32, ..?……. (a) 42 (b) 52 (c) 47 (d) 27 (e) 62

Solution: In this particular series the gap between the numbers are 5, 10, 15, ...so the next difference must be 20. Than the next number be 52. Hence option (b)

Pattern 9: Percentage increasing and decreasing pattern

Ex 13: 105, 94.5, 103.95, 93.56, ..?... (a) 102.91 (b) 102.98 (c) 102.95 (d) 103. 91 (e) none of these

Solution: In this particular Series the numbers are arranged on percentage increase and decrease pattern. As first there is 10% decrease and than 10% increase..i.e 105 – 10% of 105 = 94.5, 94.5 + 10% of 94.5 = 103.95 ..and so on. Hence option (a) 102.91 is the very next number of the series.

Pattern 10: Division or Multiplication with increasing and decreasing numbers.

Ex 14: 51975, 9450, 2100, 600, 240, 160 ? (a) 80 (b) 120 (c) 320 (d) 240 (e) 300

Solution: The pattern is

? = 160 0.5 = 320. Hence Option (c)

Ex 15: 16, 12, 18, 40.5, 121.5, 455.625 ? (a) 2050.1125 (b) 2050.2125 (c) 2050.3125 (d) 2050.4125 (e) 2050.5125

Solution: The pattern of the above Series:

16 × 0.75 = 12, 12 × 1.5 (i.e 0.75 + 0.75 = 1.5) = 18, 18 × 2.25 (i.e 1.5 + 0.75 = 2.25) = 40.5, 40.5 × 3 (i.e 2.25 + 0.75) = 121.5, ......, 455.625 × 4.50 = 2050.3125. Option (c)

Ex 16: 4,18, 48, 100, 180, 294 ? (a) 448 (b) 424 (c) 436 (d) 460 (e) 412

Solution: The pattern is, here 3rd order difference is constant.

? = 294 + 154 = 448

10 Number Series Completion

1. (c) The given series is in the pattern + 4, + 8, + 12, + 16, ..........

So, the missing term = 41 + 20 = 61

2. (d) The given series is in the pattern ×1, ×2, ×3, ×4, ..........

So, the missing term = 24 × 5= 120

3. (d) The given series is in the pattern ×2 + 1, × 2 + 2, × 2 + 3,.......

So, the missing term = 59 × 2 + 4 = 122

4. (b) The given series is in the pattern (22 – 1), (42 – 1),.......... (82 – 1), (102 – 1), (122 – 1). So, the missing term is (62 – 1) = 35

5. (c) The given series is in the pattern ÷ 6, ÷ 5, ÷ 4, ÷ 3, ÷ 2. So, the missing term is 960 ÷ 5 = 192

6. Option(e) Series is 92, 83, 74, 65, 56, 47, 38

? = 38 = 6561

7. (b) Series is 23, 43, 63, 83, 103, 123, …..

Then, ? = 143 = 2744.

8. (a) The gap is of – 9

9. (e)

10. (c) the difference between the numbers increases by 1.

11. (b)

Answer with Explanation

12. (d)

6 × 5 – 4 = 26

26 × 5 + 4 = 134

134 × 5 – 4 = 666

666 × 5 + 4 = 3334

3334 × 5 – 4 = 16666

16666 × 5 + 4 = ?

? = 83334

13. (e)

? = 294 + 154 = 448

14. (c) The series is: + 22, + 32, + 42, + 52, + 62, …..

15. (e) The series is : 232, 292, 312, 372, 412, …. (Square of prime numbers)

16. (d) The series is × 1.5, × 2, × 2.5, × 3, × 3.5

17. (a) The series is × 4 – 1, × 4 – 2, × 4 – 3, × 4 – 4, ….

18. (b) The series is + 123,+ (123 × 2),+(123 × 3),+ (123 × 4), ….

19. (c) the difference of the numbers (+ 111).

20. (d) The difference of the number is (– 121).

Concept Builder

1. (a) All nos. in the given series are squares of odd nos., except 1296

1296 = (36)2

2. (c) 13 + 14 = 27

14 + 27 = 41

27 + 41 = 68

41 + 68 = 109

68 + 109 = 117

So, 45 is the wrong number in this series.

3. (e)

4. (d) The series is:

+ 33, + 53, + 73, + 93, + 113, + 133, ………..

5. (d) 4 × 4 + (4 × 3) = 28

28 × 5 + (5 × 4) = 160
