Halfway Between 21 and 56

When you ask "What number is halfway between 21 and 56?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=56.

Halfway Between Line

To find the number halfway between 21 and 56, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 56 into our formula, we get:

(21 + 56)/2 = 38.5

Thus, the number halfway between 21 and 56 is 38.5.

To check that our answer is correct, we subtract 21 from 38.5 and subtract 38.5 from 56 and compare the two numbers:

38.5 - 21 = 17.5
56 - 38.5 = 17.5

As you can see, the halfway number is 17.5 higher than 21 and 17.5 lower than 56. Therefore, our halfway between answer of 38.5 above is correct.
