    Geometric series/geometric progression

    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?

    Undergrad How Do You Derive the Geometric Series for 1/(1-x)?

    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.
