Every term of series simplifies to 1 +  \frac{1}{(x - 1)} -  \frac{1}{(x + 1)} and x = 3, 5, 7, ...., 99 (odd numbers).

Now write first three or four terms of series, each in new line, by putting x = 3, 5, 7, 9. You can see that some terms will be cancelled out.

The final sum is given by 49 +  \frac{1}{2} -  \frac{1}{100}, it simplifies to \frac{4949}{100}

Answer = \frac{4949}{100}
