Program: n = int(input("Enter Positive Number : ")) sum = 0 sum= ((n*n)*(n+1)*(n+1))/4 print("The Sum of Series is",sum) Output: Enter Positive Number : 2 The Sum of Series is 9.0
The mathematical formula to find the sum of 1²+2²+3²+….+n² is n(n+1)(2n+1)/6 So to find the sum of series we use this formula. Program: n = int(input("Enter Positive Number : ")) sum = 0 sum= (n*(n+
