Kate writes an algebraic expression using each of the variables, x and y, only once. The first expression she writes uses x and y as factors. Then she writes another expression that uses x and y as terms. If x and y are both negative integers, write a comparison between the two expressions.

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

i believe the correct answer is b.
