Halfway Between 15 and 40

When you ask "What number is halfway between 15 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=15 and Y=40.

Halfway Between Line

To find the number halfway between 15 and 40, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 40 into our formula, we get:

(15 + 40)/2 = 27.5

Thus, the number halfway between 15 and 40 is 27.5.

To check that our answer is correct, we subtract 15 from 27.5 and subtract 27.5 from 40 and compare the two numbers:

27.5 - 15 = 12.5
40 - 27.5 = 12.5

As you can see, the halfway number is 12.5 higher than 15 and 12.5 lower than 40. Therefore, our halfway between answer of 27.5 above is correct.
