−4x − 6y = 2
B. 12x + 15y = 9
−12x + 18y = 6
C. 4x + 5y = 3
−4x − 3y = 1
D. 12x + 15y = 9
−12x − 18y = −6

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
