Erdos' Series & Prime Number Theorem Implications

[Dragonfall]

Erdos noticed that \sum(-1)^n\frac{n\log n}{p_n} diverges, where pn is the nth prime. I can't prove this conclusively. All I can say is that PNT implies that p_n~nlogn and thus the series "resembles" \sum(-1)^n.

If the terms don't go to zero, then the sum doesn't converge, right?

Oh ya, how the hell did I miss that?
