Halfway Between 21 and 71

When you ask "What number is halfway between 21 and 71?" 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=71.

Halfway Between Line

To find the number halfway between 21 and 71, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 71 into our formula, we get:

(21 + 71)/2 = 46

Thus, the number halfway between 21 and 71 is 46.

To check that our answer is correct, we subtract 21 from 46 and subtract 46 from 71 and compare the two numbers:

46 - 21 = 25
71 - 46 = 25

As you can see, the halfway number is 25 higher than 21 and 25 lower than 71. Therefore, our halfway between answer of 46 above is correct.
