the information below.

mpare to the first 5 terms in Pattern B? As
et of your answer, list the first 5 terms of each
tern.

Answer 1

See below.

Explanation:

Each term increases by 3 for A and 4 for B. Either do this calculation manually on a table, or use a spreadsheet to calculate all terms quickly.

The ten first terms for A and B are shown.

A B Difference

1 1 1 0

2 4 5 1

3 7 9 2

4 10 13 3

5 13 17 4

6 16 21 5

7 19 25 6

8 22 29 7

9 25 33 8

10 28 37 9

We can see that the difference between the two patterns is that B increases more rapidly until there is a difference of 9 by the 10th term.
