Sum of the first 5033 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 5033 square numbers, you ask? Here we will give you the formula to calculate the first 5033 square numbers and then we will show you how to calculate the first 5033 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 5033 square numbers, we enter n = 5033 into our formula to get this:

		5033(5033 + 1) × (2(5033) + 1)
		6

First, calculate each section of the numerator: 5033(5033 + 1) equals 25336122 and (2(5033) + 1) equals 10067. Therefore, the problem above becomes this:

		25336122 × 10067
		6

Next, we calculate 25336122 times 10067 which equals 255058740174. Now our problem looks like this:

		255058740174
		6

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

255058740174 ÷ 6 = 42509790029

There you go. The sum of the first 5033 square numbers is 42509790029.
