Homework Help: Dont know this power series

  1. Dec 8, 2012 #1
    I need help finishing this problem I am stuck.

    find radius of conv. and interval of convergence of the series. Ʃ k=0->∞ (1/k+1) (x)^k

    I have found all the way up to row=1 there for it is between (0,∞) so now that means that if absolute value of x<1 it converges if >1 it diverges but I forgot how I find what x is. I thought it was R which would be 1. Someone please explain to me as elementary as possible because I am no math major this is my last course/test and I will never use this again.
