If the relationship is proportional, what is the missing value from the table? -18 -15 15 18

Its -15 (B.)

Step-by-step explanation:

Just took the test and trying to help you out love.

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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
