Halfway Between 89 and 187

When you ask "What number is halfway between 89 and 187?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=187.

Halfway Between Line

To find the number halfway between 89 and 187, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 187 into our formula, we get:

(89 + 187)/2 = 138

Thus, the number halfway between 89 and 187 is 138.

To check that our answer is correct, we subtract 89 from 138 and subtract 138 from 187 and compare the two numbers:

138 - 89 = 49
187 - 138 = 49

As you can see, the halfway number is 49 higher than 89 and 49 lower than 187. Therefore, our halfway between answer of 138 above is correct.
