Halfway Between 4 and 5

When you ask "What number is halfway between 4 and 5?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=5.

Halfway Between Line

To find the number halfway between 4 and 5, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 5 into our formula, we get:

(4 + 5)/2 = 4.5

Thus, the number halfway between 4 and 5 is 4.5.

To check that our answer is correct, we subtract 4 from 4.5 and subtract 4.5 from 5 and compare the two numbers:

4.5 - 4 = 0.5
5 - 4.5 = 0.5

As you can see, the halfway number is 0.5 higher than 4 and 0.5 lower than 5. Therefore, our halfway between answer of 4.5 above is correct.
