Halfway Between 27 and 89

When you ask "What number is halfway between 27 and 89?" 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=89.

Halfway Between Line

To find the number halfway between 27 and 89, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 89 into our formula, we get:

(27 + 89)/2 = 58

Thus, the number halfway between 27 and 89 is 58.

To check that our answer is correct, we subtract 27 from 58 and subtract 58 from 89 and compare the two numbers:

58 - 27 = 31
89 - 58 = 31

As you can see, the halfway number is 31 higher than 27 and 31 lower than 89. Therefore, our halfway between answer of 58 above is correct.
