Cross multiply.

x = 7

Step-by-step explanation:

Solve for x over the real numbers:

(3 x)/(2 x - 2) = 14/8

14/8 = 7/4:

(3 x)/(2 x - 2) = 7/4

Cross multiply:

12 x = 7 (2 x - 2)

Expand out terms of the right hand side:

12 x = 14 x - 14

Subtract 14 x from both sides:

-2 x = -14

Divide both sides by -2:

 x = 7

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
