Algebra-1

To determine if the sequence is arithmetic, geometric, or neither:

1.Arithmetic Sequence:

Calculate the differences between consecutive terms:

10 - 5 = 5

7 - 10 = -3

12 - 7 = 5

The differences are 5, -3, 5, which are not constant. Therefore, the sequence is not arithmetic.

2.Geometric Sequence:

Calculate the ratios between consecutive terms:
