Halfway Between 29 and 821

When you ask "What number is halfway between 29 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=29 and Y=821.

Halfway Between Line

To find the number halfway between 29 and 821, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 29 and 821 into our formula, we get:

(29 + 821)/2 = 425

Thus, the number halfway between 29 and 821 is 425.

To check that our answer is correct, we subtract 29 from 425 and subtract 425 from 821 and compare the two numbers:

425 - 29 = 396
821 - 425 = 396

As you can see, the halfway number is 396 higher than 29 and 396 lower than 821. Therefore, our halfway between answer of 425 above is correct.
