Halfway Between 13 and 855

When you ask "What number is halfway between 13 and 855?" 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=855.

Halfway Between Line

To find the number halfway between 13 and 855, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 855 into our formula, we get:

(13 + 855)/2 = 434

Thus, the number halfway between 13 and 855 is 434.

To check that our answer is correct, we subtract 13 from 434 and subtract 434 from 855 and compare the two numbers:

434 - 13 = 421
855 - 434 = 421

As you can see, the halfway number is 421 higher than 13 and 421 lower than 855. Therefore, our halfway between answer of 434 above is correct.
