Sum of the first 737 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 737 square numbers, you ask? Here we will give you the formula to calculate the first 737 square numbers and then we will show you how to calculate the first 737 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 737 square numbers, we enter n = 737 into our formula to get this:

		737(737 + 1) × (2(737) + 1)
		6

First, calculate each section of the numerator: 737(737 + 1) equals 543906 and (2(737) + 1) equals 1475. Therefore, the problem above becomes this:

		543906 × 1475
		6

Next, we calculate 543906 times 1475 which equals 802261350. Now our problem looks like this:

		802261350
		6

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

802261350 ÷ 6 = 133710225

There you go. The sum of the first 737 square numbers is 133710225.
