Algebra-1

To determine if the sequence -5, 0, 5, 10, 15... is arithmetic, geometric, or neither:

1.Arithmetic Sequence:

Calculate the differences between consecutive terms:

0 - (-5) = 5

5 - 0 = 5

10 - 5 = 5

15 - 10 = 5

The differences between consecutive terms are all 5, which is constant. Therefore, the sequence is arithmetic.

2.Geometric Sequence:

Calculate the ratios between consecutive terms:

undefined
