Halfway Between 30 and 57

When you ask "What number is halfway between 30 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=30 and Y=57.

Halfway Between Line

To find the number halfway between 30 and 57, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 57 into our formula, we get:

(30 + 57)/2 = 43.5

Thus, the number halfway between 30 and 57 is 43.5.

To check that our answer is correct, we subtract 30 from 43.5 and subtract 43.5 from 57 and compare the two numbers:

43.5 - 30 = 13.5
57 - 43.5 = 13.5

As you can see, the halfway number is 13.5 higher than 30 and 13.5 lower than 57. Therefore, our halfway between answer of 43.5 above is correct.
