Sum of the first 5502 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 5502 square numbers, you ask? Here we will give you the formula to calculate the first 5502 square numbers and then we will show you how to calculate the first 5502 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 5502 square numbers, we enter n = 5502 into our formula to get this:

		5502(5502 + 1) × (2(5502) + 1)
		6

First, calculate each section of the numerator: 5502(5502 + 1) equals 30277506 and (2(5502) + 1) equals 11005. Therefore, the problem above becomes this:

		30277506 × 11005
		6

Next, we calculate 30277506 times 11005 which equals 333203953530. Now our problem looks like this:

		333203953530
		6

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

333203953530 ÷ 6 = 55533992255

There you go. The sum of the first 5502 square numbers is 55533992255.
