Sum of the first 362 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 362 square numbers, you ask? Here we will give you the formula to calculate the first 362 square numbers and then we will show you how to calculate the first 362 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 362 square numbers, we enter n = 362 into our formula to get this:

		362(362 + 1) × (2(362) + 1)
		6

First, calculate each section of the numerator: 362(362 + 1) equals 131406 and (2(362) + 1) equals 725. Therefore, the problem above becomes this:

		131406 × 725
		6

Next, we calculate 131406 times 725 which equals 95269350. Now our problem looks like this:

		95269350
		6

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

95269350 ÷ 6 = 15878225

There you go. The sum of the first 362 square numbers is 15878225.
