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, B, D

Step-by-step explanation:

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.

step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
