Answer 1

Explanation:

it is the first one -4/2

Answer 2

Common ratio :
`(4)/(-2)`.

Explanation:

Given : -2 , 4, -8 ,-16 ,- 32 .

to find : What is the common ratio of the geometric sequence below.

Solution : We have given

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

Common ratio :
`(second\ term)/(first\ term)`.

Common ratio :
`(4)/(-2)`.

Common ratio :
`(4)/(-2)`.

Therefore, Common ratio :
`(4)/(-2)`.
