The value of -4 - x is positive. What must be true about x ?
i need help with this asap

Step-by-step explanation:

We need to set the equation equal to 0

-4 - x > 0

+ -4   +   -4

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
