How many odd numbers between 30 and 185? You could just make a list of all the odd numbers between 30 and 185 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 30 and 185.
We start by determining the first odd number and last odd number between 30 and 185. The numbers between 30 and 185 start with 31 and end with 184. That means that the first odd number is 31 and the last odd number is 183.
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 30 and 185?"
N = (Last - First + 2) ÷ 2
N = (183 - 31 + 2) ÷ 2
N = 154 ÷ 2
N = 77
