What is the formula to find Sum of Squares of First n natural numbers?
Answer
Correct Answer : c ) [n*(n + 1)*(2n + 1)]/6
Explanation :The formulas for Sum of Natural Numbers are listed below:
Sum of First n natural numbers = [n * (n + 1)]/ 2
Sum of Squares of First n natural numbers = [n * (n + 1) * (2n + 1)]/ 6
Sum of Cubes of First n natural numbers = [n * (n + 1)/ 2]2
By looking at the formulas, the correct answer is (c)
