Halfway Between 85 and 173

When you ask "What number is halfway between 85 and 173?" 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=173.

Halfway Between Line

To find the number halfway between 85 and 173, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 173 into our formula, we get:

(85 + 173)/2 = 129

Thus, the number halfway between 85 and 173 is 129.

To check that our answer is correct, we subtract 85 from 129 and subtract 129 from 173 and compare the two numbers:

129 - 85 = 44
173 - 129 = 44

As you can see, the halfway number is 44 higher than 85 and 44 lower than 173. Therefore, our halfway between answer of 129 above is correct.
