Testing math

Testing math formatting using Replacemath, see How to do latex on my blogspot.

$latex \displaystyle S(n)=\sum_{k=1}^{n}
{\frac{1}{T_{k}}=\sum_{k=1}^{n}{\frac{6}{k(k+1)(k+2)}$

This is the result: $latex \displaystyle S(n)=\sum_{k=1}^{n}{\frac{1}{T_{k}}=\sum_{k=1}^{n}{\frac{6}{k(k+1)(k+2)}$
