Halfway Between 11 and 829

When you ask "What number is halfway between 11 and 829?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=829.

Halfway Between Line

To find the number halfway between 11 and 829, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 829 into our formula, we get:

(11 + 829)/2 = 420

Thus, the number halfway between 11 and 829 is 420.

To check that our answer is correct, we subtract 11 from 420 and subtract 420 from 829 and compare the two numbers:

420 - 11 = 409
829 - 420 = 409

As you can see, the halfway number is 409 higher than 11 and 409 lower than 829. Therefore, our halfway between answer of 420 above is correct.
