The first question would be x + (x + 4). This is because Max has $x and Keisha has (x + 4) because she has four MORE THAN Max. I am pretty sure that the second one is A, but I am not positive. The first one is right though. I hope this helps!!!

What is the equation for a geometric sequence with a first term of 2 and second term of -8?

Naya [18.7K]

A(1) = 2
r = a(2)/a(1) = -8/2 = -4

$a(n) =a {(r)}^{n - 1} \\ a(n) = 2 {( - 4)}^{n - 1}$
Answer will be D.
