Sum of the first 1634 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 1634 square numbers, you ask? Here we will give you the formula to calculate the first 1634 square numbers and then we will show you how to calculate the first 1634 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 1634 square numbers, we enter n = 1634 into our formula to get this:

		1634(1634 + 1) × (2(1634) + 1)
		6

First, calculate each section of the numerator: 1634(1634 + 1) equals 2671590 and (2(1634) + 1) equals 3269. Therefore, the problem above becomes this:

		2671590 × 3269
		6

Next, we calculate 2671590 times 3269 which equals 8733427710. Now our problem looks like this:

		8733427710
		6

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

8733427710 ÷ 6 = 1455571285

There you go. The sum of the first 1634 square numbers is 1455571285.
