How many odd numbers between 1 and 5689? You could just make a list of all the odd numbers between 1 and 5689 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 1 and 5689.
We start by determining the first odd number and last odd number between 1 and 5689. The numbers between 1 and 5689 start with 2 and end with 5688. That means that the first odd number is 3 and the last odd number is 5687.
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 1 and 5689?"
N = (Last - First + 2) ÷ 2
N = (5687 - 3 + 2) ÷ 2
N = 5686 ÷ 2
N = 2843
Odd numbers between 1 and 5689 = 2843
