How many even numbers between 145 and 173? You could just make a list of all the even numbers between 145 and 173 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 145 and 173.
We start by determining the first even number and last even number between 145 and 173. The numbers between 145 and 173 start with 146 and end with 172. That means that the first even number is 146 and the last even number is 172.
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 145 and 173?"
N = (Last - First + 2) ÷ 2
N = (172 - 146 + 2) ÷ 2
N = 28 ÷ 2
N = 14
