How many even numbers between 1 and 711? You could just make a list of all the even numbers between 1 and 711 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 even numbers there are between 1 and 711.
We start by determining the first even number and last even number between 1 and 711. The numbers between 1 and 711 start with 2 and end with 710. That means that the first even number is 2 and the last even number is 710.
Now you add 2 to the difference of the last even number and the first even number, and then divide the sum by 2. Here is the formula and the answer to "How many even numbers between 1 and 711?"
N = (Last - First + 2) ÷ 2
N = (710 - 2 + 2) ÷ 2
N = 710 ÷ 2
N = 355
Even numbers between 1 and 711 = 355
