# The Lim 1/(n+r) Problem (TOMATO Subjective 155 with some modifications)

Problem:  Evaluate: $$\lim_{n\to\infty} (\frac{1}{n+1}+\frac{1}{n+2}+\frac{1}{n+3}+…+\frac{1}{n+n})$$

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:

$$\lim_{n\to\infty} (\frac{1}{n+1}+\frac{1}{n+2}+\frac{1}{n+3}+…+\frac{1}{n+kn})$$

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