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 1253 square numbers, you ask? Here we will give you the formula to calculate the first 1253 square numbers and then we will show you how to calculate the first 1253 square numbers using the formula.
The formula to calculate the first n square numbers is displayed below:
To calculate the sum of the first 1253 square numbers, we enter n = 1253 into our formula to get this:
First, calculate each section of the numerator: 1253(1253 + 1) equals 1571262 and (2(1253) + 1) equals 2507. Therefore, the problem above becomes this:
Next, we calculate 1571262 times 2507 which equals 3939153834. Now our problem looks like this:
Finally, divide the numerator by the denominator to get our answer:
3939153834 ÷ 6 = 656525639
There you go. The sum of the first 1253 square numbers is 656525639.
