What is the sum of consecutive square numbers? Is there any formula for that? Plz answer me. 1+4+9+16+25+36....+100?

Yes,there is.

Let the number of terms be n.

Then the formula is:

[n(n+1)(2n+1)]/6

If we take 100,

[100(100+1)(2*100+1)]/6

=[(100)(101)(201)]/6

=2030100/6

=338350

Yes,there is.

[n(n+1)(2n+1)]/6

If we take 10,

[10(10+1)(2*10+1)]/6

=[(10)(11)(21)]/6

=2310/6

=385

The upper one is for 100 square not 10 square.

The one posted above this is for 10 square
