huh i hate to tell u this because you taught me how to do it but you are prolly not starting at the first term and going up

anonymous · Answer

what is the answer in a fraction in simplest form?

anonymous · Answer

imranmeah91...i think you used n=8 in the formula.

since the formula starts at n=0, the first 8 terms would be n=7.

after a little work, it looks like it would be 255/64
