Halfway Between 89 and 115

When you ask "What number is halfway between 89 and 115?" 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=115.

Halfway Between Line

To find the number halfway between 89 and 115, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 115 into our formula, we get:

(89 + 115)/2 = 102

Thus, the number halfway between 89 and 115 is 102.

To check that our answer is correct, we subtract 89 from 102 and subtract 102 from 115 and compare the two numbers:

102 - 89 = 13
115 - 102 = 13

As you can see, the halfway number is 13 higher than 89 and 13 lower than 115. Therefore, our halfway between answer of 102 above is correct.
