The sum clearly diverges. This is indisputable. The point of the claim above, that
is to demonstrate that a sum of infinitely many terms can be manipulated in a variety of ways to end up with a contradictory result. It's an artifact of trying to do computations with an infinite number of terms.
The mathematician Srinivasa Ramanujan famously demonstrated the above as follows: Suppose the series converges to some constant, call it
. Then
Now, recall the geometric power series
which holds for any
. It has derivative
Taking
, we end up with
and so
But as mentioned above, neither power series converges unless. What Ramanujan did was to consider the sum 
as a limit of the power series evaluated at :
then arrived at the conclusion that
.
But again, let's emphasize that this result is patently wrong, and only serves to demonstrate that one can't manipulate a sum of infinitely many terms like one would a sum of a finite number of terms.
