Algebra-1

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

1.Arithmetic Sequence:

Calculate the differences between consecutive terms:

-2 - 1 = -3

4 - (-2) = 6

-8 - 4 = -12

The differences are not constant, so the sequence is not arithmetic.

2.Geometric Sequence:

Calculate the ratios between consecutive terms:
