Halfway Between 21 and 704

When you ask "What number is halfway between 21 and 704?" 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=704.

Halfway Between Line

To find the number halfway between 21 and 704, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 704 into our formula, we get:

(21 + 704)/2 = 362.5

Thus, the number halfway between 21 and 704 is 362.5.

To check that our answer is correct, we subtract 21 from 362.5 and subtract 362.5 from 704 and compare the two numbers:

362.5 - 21 = 341.5
704 - 362.5 = 341.5

As you can see, the halfway number is 341.5 higher than 21 and 341.5 lower than 704. Therefore, our halfway between answer of 362.5 above is correct.
