not sure... i thoght the ratio was -2
personally i thought the geometric sequence was \[a_1r^n=8(-2)^n\]
A geometric sequence or a geometric progression is represented by \[a _{n}= ar ^{n-1}\] 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)^n-1
thanks
that is not an answer -.- though
