Halfway Between 4 and 13

When you ask "What number is halfway between 4 and 13?" 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=13.

Halfway Between Line

To find the number halfway between 4 and 13, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 13 into our formula, we get:

(4 + 13)/2 = 8.5

Thus, the number halfway between 4 and 13 is 8.5.

To check that our answer is correct, we subtract 4 from 8.5 and subtract 8.5 from 13 and compare the two numbers:

8.5 - 4 = 4.5
13 - 8.5 = 4.5

As you can see, the halfway number is 4.5 higher than 4 and 4.5 lower than 13. Therefore, our halfway between answer of 8.5 above is correct.
