Halfway Between 8 and 27

When you ask "What number is halfway between 8 and 27?" 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=27.

Halfway Between Line

To find the number halfway between 8 and 27, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 27 into our formula, we get:

(8 + 27)/2 = 17.5

Thus, the number halfway between 8 and 27 is 17.5.

To check that our answer is correct, we subtract 8 from 17.5 and subtract 17.5 from 27 and compare the two numbers:

17.5 - 8 = 9.5
27 - 17.5 = 9.5

As you can see, the halfway number is 9.5 higher than 8 and 9.5 lower than 27. Therefore, our halfway between answer of 17.5 above is correct.
