Sum of the first 524 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 524 square numbers, you ask? Here we will give you the formula to calculate the first 524 square numbers and then we will show you how to calculate the first 524 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 524 square numbers, we enter n = 524 into our formula to get this:

		524(524 + 1) × (2(524) + 1)
		6

First, calculate each section of the numerator: 524(524 + 1) equals 275100 and (2(524) + 1) equals 1049. Therefore, the problem above becomes this:

		275100 × 1049
		6

Next, we calculate 275100 times 1049 which equals 288579900. Now our problem looks like this:

		288579900
		6

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

288579900 ÷ 6 = 48096650

There you go. The sum of the first 524 square numbers is 48096650.
