The distance between point A and point B is 2 1/2 units. Which number could represent point B? A)-30. B)2.5. C)-2.0. D)3.5

C- -2.0

Step-by-step explanation:

Because going to the right would be 3, but that’s not an option.

Going to the left would get -2.0, which is option C.

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

answer: x=3 and y=4
