Halfway Between 8 and 18

When you ask "What number is halfway between 8 and 18?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=18.

Halfway Between Line

To find the number halfway between 8 and 18, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 18 into our formula, we get:

(8 + 18)/2 = 13

Thus, the number halfway between 8 and 18 is 13.

To check that our answer is correct, we subtract 8 from 13 and subtract 13 from 18 and compare the two numbers:

13 - 8 = 5
18 - 13 = 5

As you can see, the halfway number is 5 higher than 8 and 5 lower than 18. Therefore, our halfway between answer of 13 above is correct.
