## anonymous 4 years ago What is the sum of all square numbers from 0 to 101?

1. anonymous

n(n+1)(2n+1)/6 put n =101.

sum of squares of first 'n' natural or whole nos. is $\sum_{i=1}^{n} i^2 = n(n+1)(2n+1)/6$ so plug in n=101, calculate and enjoy!!

n(n+1)(2n+1)/6 put n =101.

n=101

what you wrote - that's for the first 'n' nos. @KIT3 , not the sum of *square of each no.*
