Halfway Between 15 and 57

When you ask "What number is halfway between 15 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=15 and Y=57.

Halfway Between Line

To find the number halfway between 15 and 57, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 57 into our formula, we get:

(15 + 57)/2 = 36

Thus, the number halfway between 15 and 57 is 36.

To check that our answer is correct, we subtract 15 from 36 and subtract 36 from 57 and compare the two numbers:

36 - 15 = 21
57 - 36 = 21

As you can see, the halfway number is 21 higher than 15 and 21 lower than 57. Therefore, our halfway between answer of 36 above is correct.
