Sum of the first 3002 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 3002 square numbers, you ask? Here we will give you the formula to calculate the first 3002 square numbers and then we will show you how to calculate the first 3002 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 3002 square numbers, we enter n = 3002 into our formula to get this:

		3002(3002 + 1) × (2(3002) + 1)
		6

First, calculate each section of the numerator: 3002(3002 + 1) equals 9015006 and (2(3002) + 1) equals 6005. Therefore, the problem above becomes this:

		9015006 × 6005
		6

Next, we calculate 9015006 times 6005 which equals 54135111030. Now our problem looks like this:

		54135111030
		6

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

54135111030 ÷ 6 = 9022518505

There you go. The sum of the first 3002 square numbers is 9022518505.
