Determine whether the sequence is arithmetic or geometric.

Sequence 1: 32, 16, 0, - 16, ...

Sequence 2: 32, 16, 8, 4, ...

Sequence 1: 32, 16, 0, - 16, ...

We notice that 16-32 = - 16 & 0-16 = - 16 & - 16 - (0) = - 16

Hence since the common difference is d = - 16, then it's an arithmetic progression

Sequence 2: 32, 16, 8, 4, ...

We notice that 16/32 = 1/2 & 8/16 = 1/2 & 4/8 = 1/2

Hence since the common difference is r = 1/2, then it's a geometric progression
