    if series is absolutely convergence then any kind of rearrange does not change sum of seriea

    any doubt please ask
  • Priyadarshan Choursiya thankyou
    you can rearrange many times of an absolute converge series only. other series can't rearrange.

    sir is series 1+2+3...+infinity absolutely convergent...if no. pls help how ramanujan found its sum equal to 1/12

    if series is conditionally convergent then rearrangment may change the series

    if series is conditionally convergent then we can rearranged to get desired sum

    Yes rearrangement can done only in absolutely convergent series. But not in conditionally convergent because it can even change its behavior of convergence and divergence
