How many even numbers between 1 and 222? You could just make a list of all the even numbers between 1 and 222 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 222.
We start by determining the first even number and last even number between 1 and 222. The numbers between 1 and 222 start with 2 and end with 221. That means that the first even number is 2 and the last even number is 220.
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 222?"
N = (Last - First + 2) ÷ 2
N = (220 - 2 + 2) ÷ 2
N = 220 ÷ 2
N = 110
Even numbers between 1 and 222 = 110
