**Problem: Evaluate: **

**Solution:**

**As the title suggests the modification of this problem will be, that we will solve a more general series and then use a specific value to arrive at the solution of this problem.**

**First let us consider the following limit:**

**Observe carefully that using k=1 in this limit, we get the limit that has been asked to evaluate.**

**Now**

**Let’s substitute **

**Now we can change the summand to an integral**

** (As the term is an ‘n’ free term)**

**So we see the solution is** ** **

**Substituting k=1, we get **
