You can
put this solution on YOUR website!Consider only the first 2 terms

The 2 in the Numerator and Denominator cancel leaving you with only

Expand this to 3 terms

The 2 and 3 will cancel leaving you out with

You will observe that as we increase the number of terms, the denominator increases by 1 everytime
So for 99 terms the denominator increasing by 1 will give us 100
And so your answer will be
