6x+3=2x-9 what is the answer for this problem

6x + 3 = 2x - 9

             6x - 2x = -9 - 3

                   4x = -12

                    x  = -3

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
