Halfway Between 20 and 57

When you ask "What number is halfway between 20 and 57?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=57.

Halfway Between Line

To find the number halfway between 20 and 57, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 57 into our formula, we get:

(20 + 57)/2 = 38.5

Thus, the number halfway between 20 and 57 is 38.5.

To check that our answer is correct, we subtract 20 from 38.5 and subtract 38.5 from 57 and compare the two numbers:

38.5 - 20 = 18.5
57 - 38.5 = 18.5

As you can see, the halfway number is 18.5 higher than 20 and 18.5 lower than 57. Therefore, our halfway between answer of 38.5 above is correct.
