Halfway Between 89 and 135

When you ask "What number is halfway between 89 and 135?" 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=135.

Halfway Between Line

To find the number halfway between 89 and 135, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 135 into our formula, we get:

(89 + 135)/2 = 112

Thus, the number halfway between 89 and 135 is 112.

To check that our answer is correct, we subtract 89 from 112 and subtract 112 from 135 and compare the two numbers:

112 - 89 = 23
135 - 112 = 23

As you can see, the halfway number is 23 higher than 89 and 23 lower than 135. Therefore, our halfway between answer of 112 above is correct.
