Use mathematical reasoning to choose the expression that is greater than 12. A *x 16) x3 18-1 x 15) C (3-1) x (6 x 1) D 18 = (3x1)​

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
