Step-by-step explanation:

you can't really explain this, is just have the meaning 4 less twice a number.

I wish this is the correct one and will help you!

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

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
