Halfway Between 21 and 73

When you ask "What number is halfway between 21 and 73?" 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=73.

Halfway Between Line

To find the number halfway between 21 and 73, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 73 into our formula, we get:

(21 + 73)/2 = 47

Thus, the number halfway between 21 and 73 is 47.

To check that our answer is correct, we subtract 21 from 47 and subtract 47 from 73 and compare the two numbers:

47 - 21 = 26
73 - 47 = 26

As you can see, the halfway number is 26 higher than 21 and 26 lower than 73. Therefore, our halfway between answer of 47 above is correct.
