It is a geometric sequence where you have to find the ratio miltiply only and the sequence is 9,-3,1,-1/3

The common ratio to the given geometric sequence is

Therefore common ratio is

Step-by-step explanation:

Given sequence is 9,-3,1,

Given that the given sequence is a geometric sequence

To find the common ratio of the given sequence :

Let

Common ratio

Substitute

Therefore

Common ratio

Substitute

Therefore

The common ratio to the given geometric sequence is

Therefore common ratio is

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
