Question

What is the common ratio of the geometric sequence below? -96,48, -24, 12, -6,..

Answer 1

Hey there :)

-96, 48, -24, 12, -6

Each term is divided by - 2 or multiplied by
`-(1)/(2)`


`(48)/(-96)` =
`-(1)/(2)`

`(-24)/(48)` =
`- (1)/(2)`

`(12)/(-24)` =
`- (1)/(2)`

`\frac-{6}{12}` =
`- (1)/(2)`

The common ratio is -
`(1)/(2)`
