Sum of the first 5048 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 5048 square numbers, you ask? Here we will give you the formula to calculate the first 5048 square numbers and then we will show you how to calculate the first 5048 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 5048 square numbers, we enter n = 5048 into our formula to get this:

		5048(5048 + 1) × (2(5048) + 1)
		6

First, calculate each section of the numerator: 5048(5048 + 1) equals 25487352 and (2(5048) + 1) equals 10097. Therefore, the problem above becomes this:

		25487352 × 10097
		6

Next, we calculate 25487352 times 10097 which equals 257345793144. Now our problem looks like this:

		257345793144
		6

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

257345793144 ÷ 6 = 42890965524

There you go. The sum of the first 5048 square numbers is 42890965524.
