I can't figure this out for the life of me:
A geometric series exists with the third term of 8 and the sixth term of 128, what is the geometric series?
I could use some help with this question:
Derive the geometric series representation of 1/(1-x) by finding a0, a1,
a2,... such that
(1-x)(a0+a1x+a2x^2+a3X^3+...)=1
Thank you.
