5) find the sum if A1=256, r = 3/4, and n=9
I put it in the calculator : (256-256x3/4^9)/(1-3/4)
My answer is 242461/256
6) find the sum if A1=625, R = 2/5, n=8
I put it in the calculator: (625-625x2/5^8)/(1-2/5)
My answer is 130123/125
7) Find the sum if A2 = -12, A5 = -324, n = 10
I did two or three steps and got -480.
Something really doesn't seem right. If someone could check this and show me what I am doing wrong I would be very greatful.
