Halfway Between 45 and 173

When you ask "What number is halfway between 45 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=45 and Y=173.

Halfway Between Line

To find the number halfway between 45 and 173, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 173 into our formula, we get:

(45 + 173)/2 = 109

Thus, the number halfway between 45 and 173 is 109.

To check that our answer is correct, we subtract 45 from 109 and subtract 109 from 173 and compare the two numbers:

109 - 45 = 64
173 - 109 = 64

As you can see, the halfway number is 64 higher than 45 and 64 lower than 173. Therefore, our halfway between answer of 109 above is correct.
