How many odd numbers between 2 and 4? You could just make a list of all the odd numbers between 2 and 4 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 2 and 4.
We start by determining the first odd number and last odd number between 2 and 4. The numbers between 2 and 4 start with 3 and end with 3. That means that the first odd number is 3 and the last odd number is 3.
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 2 and 4?"
N = (Last - First + 2) ÷ 2
N = (3 - 3 + 2) ÷ 2
N = 2 ÷ 2
N = 1
Odd numbers between 2 and 4 = 1
