Which sequences are geometric? Select three options.
–2.7, –9, –30, –100, ...
–1, 2.5, –6.25, 15.625, ...
9.1, 9.2, 9.3, 9.4, ...
8, 0.8, 0.08, 0.008, ...
4, –4, –12, –20, ...

A geometric sequence has terms that are multiplied or divided by the same factor each time, as opposed to an arithmetic, which is addition or subtraction.

So if we divide the terms by each other, we can tell.

-9/-2.7 = -30/-9 = -100/-3, so A is geometric.

2.5/-1 = -6.25/2.5 = 15.625/-6.25, so B is geometric.

9.2/9.1 ≠ 9.3/9.2 ! C is an arithmetic sequence.

.8/8 = .08/.8 = .008/.08, so D is geometric.

-4/4 ≠ -12/-4 ! E is an arithmetic sequence.
