Suppose
$S = 1 + 1 + 1 + 1 ....$
and hence we can write
$S = 1 + S$
therefore,
$ 1 = 0$
This seems absurd to me but where am I going wrong here? or is it some paradox
Although I am not sure I helped - I've search for any version, you asked about good version.....
It's quite likely that there are others posts about this (and maybe some variations) - but I cannot think of some other reasonable way to search for them right now.
I'll add that I do not see anything on this topic among deleted questions with these two tags. But deleted questions are an unlikely source of good material, anyway.
