Sum of the first 1494 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 1494 square numbers, you ask? Here we will give you the formula to calculate the first 1494 square numbers and then we will show you how to calculate the first 1494 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 1494 square numbers, we enter n = 1494 into our formula to get this:

		1494(1494 + 1) × (2(1494) + 1)
		6

First, calculate each section of the numerator: 1494(1494 + 1) equals 2233530 and (2(1494) + 1) equals 2989. Therefore, the problem above becomes this:

		2233530 × 2989
		6

Next, we calculate 2233530 times 2989 which equals 6676021170. Now our problem looks like this:

		6676021170
		6

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

6676021170 ÷ 6 = 1112670195

There you go. The sum of the first 1494 square numbers is 1112670195.
