Halfway Between 43 and 821

When you ask "What number is halfway between 43 and 821?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=43 and Y=821.

Halfway Between Line

To find the number halfway between 43 and 821, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 821 into our formula, we get:

(43 + 821)/2 = 432

Thus, the number halfway between 43 and 821 is 432.

To check that our answer is correct, we subtract 43 from 432 and subtract 432 from 821 and compare the two numbers:

432 - 43 = 389
821 - 432 = 389

As you can see, the halfway number is 389 higher than 43 and 389 lower than 821. Therefore, our halfway between answer of 432 above is correct.
