Halfway Between 13 and 829

When you ask "What number is halfway between 13 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=13 and Y=829.

Halfway Between Line

To find the number halfway between 13 and 829, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 829 into our formula, we get:

(13 + 829)/2 = 421

Thus, the number halfway between 13 and 829 is 421.

To check that our answer is correct, we subtract 13 from 421 and subtract 421 from 829 and compare the two numbers:

421 - 13 = 408
829 - 421 = 408

As you can see, the halfway number is 408 higher than 13 and 408 lower than 829. Therefore, our halfway between answer of 421 above is correct.
