Halfway Between 21 and 43

When you ask "What number is halfway between 21 and 43?" 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=43.

Halfway Between Line

To find the number halfway between 21 and 43, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 43 into our formula, we get:

(21 + 43)/2 = 32

Thus, the number halfway between 21 and 43 is 32.

To check that our answer is correct, we subtract 21 from 32 and subtract 32 from 43 and compare the two numbers:

32 - 21 = 11
43 - 32 = 11

As you can see, the halfway number is 11 higher than 21 and 11 lower than 43. Therefore, our halfway between answer of 32 above is correct.
