The family of natural numbers includes all the counting numbers, starting from 1 till infinity. If n consecutive natural numbers are 1, 2, 3, 4, …, n, then the sum of squared ‘n’ consecutive natural numbers is represented by 12 + 22 + 32 + … + n2.
In short, it is denoted by the notation Σn2. The formula for the addition of squares of natural numbers is given below:
Σn2 = [n(n+1)(2n+1)]/6
The formula to calculate the sum of cubes of “n” natural numbers is Sn = [n(n+1)/2]2.
