Is this complementary, supplementary, or neithe

Neither

Step-by-step explanation:

Complementary adds up to 90 always

Supplementary adds up to 180 always

These angles do not do the following, therefore it's neither.

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
