    Finding the Closed Form of a Summation for k*z-k: Step-by-Step Solution

    LCKurtz , i can't understand your post.I know the closed form of geometric series =\frac{FirstTerm} {1 - CommonRatio} CommonRatio = termn / termn-1 but in my problem , the 'CommonRatio' isn't fixed term4/term3 not equal to term3/term2

    Finding the Closed Form of a Summation for k*z-k: Step-by-Step Solution

    Please please, I need solution hello every one I have this summation in my book infinity \sum k*z-k k=0 my solution: infinity \sum k*z-k = z-1+2z-2+3z-3+... k=0 please i want the closed form (step-by-step)
