How many odd numbers between 1 and 4557? You could just make a list of all the odd numbers between 1 and 4557 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 4557.
We start by determining the first odd number and last odd number between 1 and 4557. The numbers between 1 and 4557 start with 2 and end with 4556. That means that the first odd number is 3 and the last odd number is 4555.
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 4557?"
N = (Last - First + 2) ÷ 2
N = (4555 - 3 + 2) ÷ 2
N = 4554 ÷ 2
N = 2277
Odd numbers between 1 and 4557 = 2277
