Question

The first three terms of an arithmetic sequence are as follows.

37, 29,21
Find the next two terms of this sequence.

Answer 1

13, 5

Explanation:

First, we find the common difference.

d = 29 - 37 = -8

Now we add -8 to the last term to find the next term.

21 + (-8) = 13

13 + (-8) = 5

Answer: 13, 5
