Halfway Between 5 and 15

When you ask "What number is halfway between 5 and 15?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=15.

Halfway Between Line

To find the number halfway between 5 and 15, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 15 into our formula, we get:

(5 + 15)/2 = 10

Thus, the number halfway between 5 and 15 is 10.

To check that our answer is correct, we subtract 5 from 10 and subtract 10 from 15 and compare the two numbers:

10 - 5 = 5
15 - 10 = 5

As you can see, the halfway number is 5 higher than 5 and 5 lower than 15. Therefore, our halfway between answer of 10 above is correct.
