Halfway Between 13 and 857

When you ask "What number is halfway between 13 and 857?" 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=857.

Halfway Between Line

To find the number halfway between 13 and 857, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 857 into our formula, we get:

(13 + 857)/2 = 435

Thus, the number halfway between 13 and 857 is 435.

To check that our answer is correct, we subtract 13 from 435 and subtract 435 from 857 and compare the two numbers:

435 - 13 = 422
857 - 435 = 422

As you can see, the halfway number is 422 higher than 13 and 422 lower than 857. Therefore, our halfway between answer of 435 above is correct.
