Homework Help: Where does this sequence converge?

  1. Dec 11, 2011 #1
    1. The problem statement, all variables and given/known data
    Does the sequence 1 + .4 + .16 +.064 Converge and where if so?

    So I started this problem out by making the a series equation
    Ʃ.4^n
    Where n=0
    So since i believe this is the series equation for this sequence I now know that it does in fact converge because -1 < .4 ≤ 1. So i know that this converges but how do i find out exactly where it converges?
