Halfway Between 85 and 123

When you ask "What number is halfway between 85 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=85 and Y=123.

Halfway Between Line

To find the number halfway between 85 and 123, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 123 into our formula, we get:

(85 + 123)/2 = 104

Thus, the number halfway between 85 and 123 is 104.

To check that our answer is correct, we subtract 85 from 104 and subtract 104 from 123 and compare the two numbers:

104 - 85 = 19
123 - 104 = 19

As you can see, the halfway number is 19 higher than 85 and 19 lower than 123. Therefore, our halfway between answer of 104 above is correct.
