Someone please help me I really need help me step by step and answer

1) subtract from both sides

2) divide both sides by -2

(1)take the square root of both sides

(2) simplify

5) regroup terms

6) switch sides

7) break down the problem into these 2 equations

8) solve the 1st equation

(1) add 4 to both sides

(2) regroup terms

9) solve the 2nd equation

(1) add 4 to both sides

(2) regroup terms

10) collect all solutions

that's your answer!

I hope it understand you

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

could you provide figure.
