How many even numbers between 1 and 2438? You could just make a list of all the even numbers between 1 and 2438 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 2438.
We start by determining the first even number and last even number between 1 and 2438. The numbers between 1 and 2438 start with 2 and end with 2437. That means that the first even number is 2 and the last even number is 2436.
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 2438?"
N = (Last - First + 2) ÷ 2
N = (2436 - 2 + 2) ÷ 2
N = 2436 ÷ 2
N = 1218
Even numbers between 1 and 2438 = 1218
