Sum of the first 979 square numbers

We define square numbers as numbers that when squared will equal a whole number. Thus, the list of the first square numbers starts with 1, 4, 9, 16, and so on.

What is the sum of the first 979 square numbers, you ask? Here we will give you the formula to calculate the first 979 square numbers and then we will show you how to calculate the first 979 square numbers using the formula.

The formula to calculate the first n square numbers is displayed below:

		n(n + 1) × (2(n) + 1)
		6

To calculate the sum of the first 979 square numbers, we enter n = 979 into our formula to get this:

		979(979 + 1) × (2(979) + 1)
		6

First, calculate each section of the numerator: 979(979 + 1) equals 959420 and (2(979) + 1) equals 1959. Therefore, the problem above becomes this:

		959420 × 1959
		6

Next, we calculate 959420 times 1959 which equals 1879503780. Now our problem looks like this:

		1879503780
		6

Finally, divide the numerator by the denominator to get our answer:

1879503780 ÷ 6 = 313250630

There you go. The sum of the first 979 square numbers is 313250630.
