How many even numbers between 1 and 8000? You could just make a list of all the even numbers between 1 and 8000 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 8000.
We start by determining the first even number and last even number between 1 and 8000. The numbers between 1 and 8000 start with 2 and end with 7999. That means that the first even number is 2 and the last even number is 7998.
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 8000?"
N = (Last - First + 2) ÷ 2
N = (7998 - 2 + 2) ÷ 2
N = 7998 ÷ 2
N = 3999
Even numbers between 1 and 8000 = 3999
