Halfway Between 11 and 871

When you ask "What number is halfway between 11 and 871?" 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=871.

Halfway Between Line

To find the number halfway between 11 and 871, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 871 into our formula, we get:

(11 + 871)/2 = 441

Thus, the number halfway between 11 and 871 is 441.

To check that our answer is correct, we subtract 11 from 441 and subtract 441 from 871 and compare the two numbers:

441 - 11 = 430
871 - 441 = 430

As you can see, the halfway number is 430 higher than 11 and 430 lower than 871. Therefore, our halfway between answer of 441 above is correct.
