The variance of the first n natural numbers is

Given an integer N , the task is to find the variance of the first N natural numbers. Variance is used to determine how far the data is spread from their average value. It is generally represented by symbol? Input: 4 Output: 1. Naive approach: The simple approach to solve this problem is to first calculate the Mean value of the first N natural numbers and then, traverse over the range [1, N] and calculate the variance. Efficient solution: The above solution can be optimized by simplifying the above-mentioned formulas of Mean and Variance and using the properties of sum of the first N natural number and the sum of the squares of the first N natural numbers , as shown below.

In addition, we will also assume the following property of the natural numbers. To paraphrase the previous property, every nonempty subset of positive integers has a smallest element. The principle of mathematical induction is a useful tool for proving facts about sequences. Suppose the following conditions hold:. Suppose conditions a and b hold. This is a contradiction, so the conclusion follows. We will refer to this principle as mathematical induction or simply induction.
