Sum of the first 5012 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 5012 square numbers, you ask? Here we will give you the formula to calculate the first 5012 square numbers and then we will show you how to calculate the first 5012 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 5012 square numbers, we enter n = 5012 into our formula to get this:

		5012(5012 + 1) × (2(5012) + 1)
		6

First, calculate each section of the numerator: 5012(5012 + 1) equals 25125156 and (2(5012) + 1) equals 10025. Therefore, the problem above becomes this:

		25125156 × 10025
		6

Next, we calculate 25125156 times 10025 which equals 251879688900. Now our problem looks like this:

		251879688900
		6

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

251879688900 ÷ 6 = 41979948150

There you go. The sum of the first 5012 square numbers is 41979948150.
