Course Introduction：In this article, we will look at different ways to calculate the sum of a sequence - (n^2-1^2)+2(n^2-2^2)+….n(n^2-n^2). In the first method, we will calculate the sequence sum for each i in the range 1 to n one by one and add it to the final sum. In the second approach, we will derive a mathematical formula to calculate the sum of a given series, which will reduce the time complexity of the program from O(n) to O(1). Problem Statement − We are given a number “n” and our task is to calculate the sum of the given sequence (n^2-1^2)+2(n^2-2^2)+….n(n^2 -n^2). Example input − number = 5 output – when n = 5, series (n^2-1^2)
