Series in Summation Notation
We must try to find a general formula for each term and then use summation to generalize the sum of all the terms for any value of n, the term number.
The series is
The difference between consecutive terms will be computed:
We can see that
Applying summation on both sides:
Knowing that
Similarly, the sum of the left side is found to be
Replacing into the above equation, we find
Solving
Having the general term, the series is expressed as
For n=0 to infinity
