Halfway Between 21 and 47

When you ask "What number is halfway between 21 and 47?" 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=47.

Halfway Between Line

To find the number halfway between 21 and 47, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 47 into our formula, we get:

(21 + 47)/2 = 34

Thus, the number halfway between 21 and 47 is 34.

To check that our answer is correct, we subtract 21 from 34 and subtract 34 from 47 and compare the two numbers:

34 - 21 = 13
47 - 34 = 13

As you can see, the halfway number is 13 higher than 21 and 13 lower than 47. Therefore, our halfway between answer of 34 above is correct.
