Answer:
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.
