Halfway Between 89 and 118

When you ask "What number is halfway between 89 and 118?" 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=118.

Halfway Between Line

To find the number halfway between 89 and 118, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 118 into our formula, we get:

(89 + 118)/2 = 103.5

Thus, the number halfway between 89 and 118 is 103.5.

To check that our answer is correct, we subtract 89 from 103.5 and subtract 103.5 from 118 and compare the two numbers:

103.5 - 89 = 14.5
118 - 103.5 = 14.5

As you can see, the halfway number is 14.5 higher than 89 and 14.5 lower than 118. Therefore, our halfway between answer of 103.5 above is correct.
