Homework Help: Transition from the second step to the third step?

  1. Apr 20, 2016 #1
    1. The problem statement, all variables and given/known data
    How do you change from the second step to the third step?

    2. Relevant equations

    3. The attempt at a solution
    My guess is that it has something to do with the geometric series. I am not sure how to proceed.

    Hello, your majesty, :welcome:

    That is not a problem statement in your 1. !
    Nor is 2. a relevant equation !
    And 3 is a guess, not an attempt at solution.

    What's this about ? Could you please read the guidelines ?
