What would this be fill it in ? If you know it :)

for the first one y is -4

second one x is -1

third one y is 2

aD for the last one x is 1!

sorry for any mistakes if there are, but I hope this helped!! :D

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
