Sum of the first 948 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 948 square numbers, you ask? Here we will give you the formula to calculate the first 948 square numbers and then we will show you how to calculate the first 948 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 948 square numbers, we enter n = 948 into our formula to get this:

		948(948 + 1) × (2(948) + 1)
		6

First, calculate each section of the numerator: 948(948 + 1) equals 899652 and (2(948) + 1) equals 1897. Therefore, the problem above becomes this:

		899652 × 1897
		6

Next, we calculate 899652 times 1897 which equals 1706639844. Now our problem looks like this:

		1706639844
		6

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

1706639844 ÷ 6 = 284439974

There you go. The sum of the first 948 square numbers is 284439974.
