Sum of the first 2462 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 2462 square numbers, you ask? Here we will give you the formula to calculate the first 2462 square numbers and then we will show you how to calculate the first 2462 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 2462 square numbers, we enter n = 2462 into our formula to get this:

		2462(2462 + 1) × (2(2462) + 1)
		6

First, calculate each section of the numerator: 2462(2462 + 1) equals 6063906 and (2(2462) + 1) equals 4925. Therefore, the problem above becomes this:

		6063906 × 4925
		6

Next, we calculate 6063906 times 4925 which equals 29864737050. Now our problem looks like this:

		29864737050
		6

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

29864737050 ÷ 6 = 4977456175

There you go. The sum of the first 2462 square numbers is 4977456175.
