Halfway Between 89 and 123

When you ask "What number is halfway between 89 and 123?" 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=123.

Halfway Between Line

To find the number halfway between 89 and 123, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 123 into our formula, we get:

(89 + 123)/2 = 106

Thus, the number halfway between 89 and 123 is 106.

To check that our answer is correct, we subtract 89 from 106 and subtract 106 from 123 and compare the two numbers:

106 - 89 = 17
123 - 106 = 17

As you can see, the halfway number is 17 higher than 89 and 17 lower than 123. Therefore, our halfway between answer of 106 above is correct.
