Halfway Between 13 and 827

When you ask "What number is halfway between 13 and 827?" 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=827.

Halfway Between Line

To find the number halfway between 13 and 827, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 827 into our formula, we get:

(13 + 827)/2 = 420

Thus, the number halfway between 13 and 827 is 420.

To check that our answer is correct, we subtract 13 from 420 and subtract 420 from 827 and compare the two numbers:

420 - 13 = 407
827 - 420 = 407

As you can see, the halfway number is 407 higher than 13 and 407 lower than 827. Therefore, our halfway between answer of 420 above is correct.
