Halfway Between 18 and 40

When you ask "What number is halfway between 18 and 40?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=40.

Halfway Between Line

To find the number halfway between 18 and 40, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 40 into our formula, we get:

(18 + 40)/2 = 29

Thus, the number halfway between 18 and 40 is 29.

To check that our answer is correct, we subtract 18 from 29 and subtract 29 from 40 and compare the two numbers:

29 - 18 = 11
40 - 29 = 11

As you can see, the halfway number is 11 higher than 18 and 11 lower than 40. Therefore, our halfway between answer of 29 above is correct.
