I am a little confused as to notation for convergence. I included a picture too.(adsbygoogle = window.adsbygoogle || []).push({});

If you take a look it says "then the series Ʃan is divergent"

Does the "Ʃan" just mean the convergence as to the sum of the series, or the lim an as n→ ∞ nth term?

I believe it is the sum of the series but I just want to make sure.

As for the physical meaning of Ʃan I think that's related to the area, but what is the physical meaning of taking the lim an as n→ ∞ for the nth term?

Thanks
