Halfway Between 57 and 172

When you ask "What number is halfway between 57 and 172?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=57 and Y=172.

Halfway Between Line

To find the number halfway between 57 and 172, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 57 and 172 into our formula, we get:

(57 + 172)/2 = 114.5

Thus, the number halfway between 57 and 172 is 114.5.

To check that our answer is correct, we subtract 57 from 114.5 and subtract 114.5 from 172 and compare the two numbers:

114.5 - 57 = 57.5
172 - 114.5 = 57.5

As you can see, the halfway number is 57.5 higher than 57 and 57.5 lower than 172. Therefore, our halfway between answer of 114.5 above is correct.
