I answered a question like a month back concerning the radius of convergence of a specific series where the poster had a polynomial so I pointed out that convergence is all of $\mathbb{R}$, not the most interesting question but since nothing was done until today I am confused by its deletion. My answer to that question was accepted and up voted a couple of times which means the poster themselves can not have deleted it according to the help center post.
I cannot see the reasons for deletion so could someone please explain why it was deleted now?
