personally i thought the geometric sequence was \[a_1r^n=8(2)^n\]

A geometric sequence or a geometric progression is represented by \[a _{n}= ar ^{n1}\] Where n is the number of the term, a is the first term and r is the common ratio. The first term of a geometric sequence is always a, so in your case, that would be 8 Now you need to find 'r' First term = a = 8 Second term = ar = 8r =16 Third term = ar^2 = 8r^2 = 32 Divide the second term by the first term and you get r = 2 So the correct answer is =8(−2)^n1
