Halfway Between 30 and 822

When you ask "What number is halfway between 30 and 822?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=822.

Halfway Between Line

To find the number halfway between 30 and 822, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 822 into our formula, we get:

(30 + 822)/2 = 426

Thus, the number halfway between 30 and 822 is 426.

To check that our answer is correct, we subtract 30 from 426 and subtract 426 from 822 and compare the two numbers:

426 - 30 = 396
822 - 426 = 396

As you can see, the halfway number is 396 higher than 30 and 396 lower than 822. Therefore, our halfway between answer of 426 above is correct.
