Halfway Between 21 and 38

When you ask "What number is halfway between 21 and 38?" 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=38.

Halfway Between Line

To find the number halfway between 21 and 38, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 38 into our formula, we get:

(21 + 38)/2 = 29.5

Thus, the number halfway between 21 and 38 is 29.5.

To check that our answer is correct, we subtract 21 from 29.5 and subtract 29.5 from 38 and compare the two numbers:

29.5 - 21 = 8.5
38 - 29.5 = 8.5

As you can see, the halfway number is 8.5 higher than 21 and 8.5 lower than 38. Therefore, our halfway between answer of 29.5 above is correct.
