Halfway Between 11 and 855

When you ask "What number is halfway between 11 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=11 and Y=855.

Halfway Between Line

To find the number halfway between 11 and 855, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 855 into our formula, we get:

(11 + 855)/2 = 433

Thus, the number halfway between 11 and 855 is 433.

To check that our answer is correct, we subtract 11 from 433 and subtract 433 from 855 and compare the two numbers:

433 - 11 = 422
855 - 433 = 422

As you can see, the halfway number is 422 higher than 11 and 422 lower than 855. Therefore, our halfway between answer of 433 above is correct.
