How many odd numbers between 125 and 155? You could just make a list of all the odd numbers between 125 and 155 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 odd numbers there are between 125 and 155.
We start by determining the first odd number and last odd number between 125 and 155. The numbers between 125 and 155 start with 126 and end with 154. That means that the first odd number is 127 and the last odd number is 153.
Now you add 2 to the difference of the last odd number and the first odd number, and then divide the sum by 2. Here is the formula and the answer to "How many odd numbers between 125 and 155?"
N = (Last - First + 2) ÷ 2
N = (153 - 127 + 2) ÷ 2
