Halfway Between 45 and 57

When you ask "What number is halfway between 45 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=45 and Y=57.

Halfway Between Line

To find the number halfway between 45 and 57, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 57 into our formula, we get:

(45 + 57)/2 = 51

Thus, the number halfway between 45 and 57 is 51.

To check that our answer is correct, we subtract 45 from 51 and subtract 51 from 57 and compare the two numbers:

51 - 45 = 6
57 - 51 = 6

As you can see, the halfway number is 6 higher than 45 and 6 lower than 57. Therefore, our halfway between answer of 51 above is correct.
