How many even numbers between 1 and 582? You could just make a list of all the even numbers between 1 and 582 and then count them, but what fun would that be?
Instead, we have created this simple process with a small formula to calculate exactly how many even numbers there are between 1 and 582.
We start by determining the first even number and last even number between 1 and 582. The numbers between 1 and 582 start with 2 and end with 581. That means that the first even number is 2 and the last even number is 580.
Now you add 2 to the difference of the last even number and the first even number, and then divide the sum by 2. Here is the formula and the answer to "How many even numbers between 1 and 582?"
N = (Last - First + 2) ÷ 2
N = (580 - 2 + 2) ÷ 2
N = 580 ÷ 2
N = 290
Even numbers between 1 and 582 = 290
