Algebra-1

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

1.Arithmetic Sequence:

Calculate the differences between consecutive terms:

50 - 100 = -50

25 - 50 = -25

12.5 - 25 = -12.5

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

2.Geometric Sequence:

Calculate the ratios between consecutive terms:
