Halfway Between 12 and 870

When you ask "What number is halfway between 12 and 870?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=870.

Halfway Between Line

To find the number halfway between 12 and 870, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 870 into our formula, we get:

(12 + 870)/2 = 441

Thus, the number halfway between 12 and 870 is 441.

To check that our answer is correct, we subtract 12 from 441 and subtract 441 from 870 and compare the two numbers:

441 - 12 = 429
870 - 441 = 429

As you can see, the halfway number is 429 higher than 12 and 429 lower than 870. Therefore, our halfway between answer of 441 above is correct.
