Sum of the first 1310 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 1310 square numbers, you ask? Here we will give you the formula to calculate the first 1310 square numbers and then we will show you how to calculate the first 1310 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 1310 square numbers, we enter n = 1310 into our formula to get this:

		1310(1310 + 1) × (2(1310) + 1)
		6

First, calculate each section of the numerator: 1310(1310 + 1) equals 1717410 and (2(1310) + 1) equals 2621. Therefore, the problem above becomes this:

		1717410 × 2621
		6

Next, we calculate 1717410 times 2621 which equals 4501331610. Now our problem looks like this:

		4501331610
		6

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

4501331610 ÷ 6 = 750221935

There you go. The sum of the first 1310 square numbers is 750221935.
