Sum of the first 1488 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 1488 square numbers, you ask? Here we will give you the formula to calculate the first 1488 square numbers and then we will show you how to calculate the first 1488 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 1488 square numbers, we enter n = 1488 into our formula to get this:

		1488(1488 + 1) × (2(1488) + 1)
		6

First, calculate each section of the numerator: 1488(1488 + 1) equals 2215632 and (2(1488) + 1) equals 2977. Therefore, the problem above becomes this:

		2215632 × 2977
		6

Next, we calculate 2215632 times 2977 which equals 6595936464. Now our problem looks like this:

		6595936464
		6

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

6595936464 ÷ 6 = 1099322744

There you go. The sum of the first 1488 square numbers is 1099322744.
