How many even numbers between 73 and 82? You could just make a list of all the even numbers between 73 and 82 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 73 and 82.
We start by determining the first even number and last even number between 73 and 82. The numbers between 73 and 82 start with 74 and end with 81. That means that the first even number is 74 and the last even number is 80.
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 73 and 82?"
N = (Last - First + 2) ÷ 2
N = (80 - 74 + 2) ÷ 2
N = 8 ÷ 2
N = 4
