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