About Sum of Squares Calculator

The Sum of Squares Calculator is used to calculate the sum of first n squares or the sum of consecutive square numbers from n₁² to n₂².

The sum of the first n square numbers is equal to:

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

The sum of consecutive square numbers from n₁² to n₂² is equal to:

n₁² + (n₁ + 1)² + ... + n₂² = n₂(n₂ + 1)(2n₂ + 1) / 6 - n₁(n₁ - 1)(2n₁ - 1) / 6
