Halfway Between 27 and 189

When you ask "What number is halfway between 27 and 189?" 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=189.

Halfway Between Line

To find the number halfway between 27 and 189, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 189 into our formula, we get:

(27 + 189)/2 = 108

Thus, the number halfway between 27 and 189 is 108.

To check that our answer is correct, we subtract 27 from 108 and subtract 108 from 189 and compare the two numbers:

108 - 27 = 81
189 - 108 = 81

As you can see, the halfway number is 81 higher than 27 and 81 lower than 189. Therefore, our halfway between answer of 108 above is correct.
