Question

Tell whether the sequence is arithmetic. If it is, identify the common difference -7.-3.1.5....​

Answer 1

9514 1404 393

Answer:

yes, 4

Explanation:

We assume your sequence is supposed to be ...

-7, -3, 1, 5

First differences are ...

-3 -(-7) = 4

1 -(-3) = 4

5 -1 = 4

These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.
