Sum of the first 574 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 574 square numbers, you ask? Here we will give you the formula to calculate the first 574 square numbers and then we will show you how to calculate the first 574 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 574 square numbers, we enter n = 574 into our formula to get this:

		574(574 + 1) × (2(574) + 1)
		6

First, calculate each section of the numerator: 574(574 + 1) equals 330050 and (2(574) + 1) equals 1149. Therefore, the problem above becomes this:

		330050 × 1149
		6

Next, we calculate 330050 times 1149 which equals 379227450. Now our problem looks like this:

		379227450
		6

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

379227450 ÷ 6 = 63204575

There you go. The sum of the first 574 square numbers is 63204575.
