How many even numbers between 64 and 135? You could just make a list of all the even numbers between 64 and 135 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 64 and 135.
We start by determining the first even number and last even number between 64 and 135. The numbers between 64 and 135 start with 65 and end with 134. That means that the first even number is 66 and the last even number is 134.
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 64 and 135?"
N = (Last - First + 2) ÷ 2
N = (134 - 66 + 2) ÷ 2
N = 70 ÷ 2
N = 35
Even numbers between 64 and 135 = 35
