Can you do a series on the power series

Hi Bello! What do you mean by "power series"?

[Mia Temma](https://hashnode.com/@miatemma) I mean to check for convergence of the harmonics and other sequence like the zeta sequence

[Bello Mahmud](https://hashnode.com/@Mahmudsudo) Hi Bello, that's an interesting idea, I will check which resources I can find on that!( Regarding the zeta function, you can also find an approximation on the Rosetta code: [rosettacode.org/wiki/Sum\_of\_a\_series](https://rosettacode.org/wiki/Sum_of_a_series#PicoLisp)
