How many even numbers between 1 and 3879? You could just make a list of all the even numbers between 1 and 3879 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 3879.
We start by determining the first even number and last even number between 1 and 3879. The numbers between 1 and 3879 start with 2 and end with 3878. That means that the first even number is 2 and the last even number is 3878.
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 3879?"
N = (Last - First + 2) ÷ 2
N = (3878 - 2 + 2) ÷ 2
N = 3878 ÷ 2
N = 1939
Even numbers between 1 and 3879 = 1939
