Halfway Between 27 and 81

When you ask "What number is halfway between 27 and 81?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=27 and Y=81.

Halfway Between Line

To find the number halfway between 27 and 81, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 81 into our formula, we get:

(27 + 81)/2 = 54

Thus, the number halfway between 27 and 81 is 54.

To check that our answer is correct, we subtract 27 from 54 and subtract 54 from 81 and compare the two numbers:

54 - 27 = 27
81 - 54 = 27

As you can see, the halfway number is 27 higher than 27 and 27 lower than 81. Therefore, our halfway between answer of 54 above is correct.
