Question

Tell whether the sequence is arithmetic. If it​ is, identify the common difference. -5, -2, 1, 4

Answer 1

arithmetic sequence

Explanation:

The terms have a common difference between consecutive terms , that is

- 2 - (- 5) = - 2 + 5 = 3

1 - (- 2) = 1 + 2 = 3

4 - 1 = 3

Since there is a common difference d = 3

Then the sequence is arithmetic
