Geometric Sequences

Geometric Sequence

• A geometric sequence is a sequence in which the quotient of any two consecutive terms is the same.

2, 4, 8, 16, 32, … 3125, 625, 125, 25, 5, …

• The quotient is called the common ratio.

Write the next three terms of each sequence. Then state whether each

sequence is geometric.

...,80,40,20,10,5.B

...,3
