Question

Geometric SequencesDetermise if the sequence is geometric. If it is, find the common ratio.3 points-7, -1, 5, 11,...O Not geometricGeometric; common ratio: 6O Geometric; common ratio -7Geometric; common ratio: 11

Answer 1

The common ratio is found dividing two consecutive terms, as follows:

-1/-7 = 1/7

5/-1 = -5

11/5

Given that these results are all different, then it is not a geometric sequence
