Sports Banquet Pattern
Gilles and Aceena are arranging an academic and sports banquet.
They want to know how many guests can be seated in different table arrangements

Sports Banquet Pattern
The arrangement pattern is below:The circles show where guests can sit.
How many guests can sit in each arrangement?

6 10 14

Sports Banquet Pattern
Can you predict how many people can sit at 10 tables? At 20?
![Page 6: Investigate and Describe Patterns](https://reader036.vdocument.in/reader036/viewer/2022082600/5a4d1b0e7f8b9ab05998d92f/html5/thumbnails/6.jpg)

Here is the visual for 10 and 20 tables
42 people
82 people

Is there a way to figure this out without drawing the pattern?
Organize the
information you have?
Yeah! …and look for a pattern in
the numbers!

Let’s arrange the information we
already have for this pattern in a table.

guests

Can you use that pattern to predict the number of guests at 10 and 20 tables?

How does the number of blue chairs relate to the table number?

Is this the pattern?
Sports Banquet Pattern
So…4 chairs for each table plus the 2 on the ends!
Can we write this symbolically?
4 x the number of tables + 2
Let’s use “t” to stand for the number of tables
4t + 2Let’s test this
expression with our information
