Halfway Between 80 and 870

When you ask "What number is halfway between 80 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=80 and Y=870.

Halfway Between Line

To find the number halfway between 80 and 870, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 870 into our formula, we get:

(80 + 870)/2 = 475

Thus, the number halfway between 80 and 870 is 475.

To check that our answer is correct, we subtract 80 from 475 and subtract 475 from 870 and compare the two numbers:

475 - 80 = 395
870 - 475 = 395

As you can see, the halfway number is 395 higher than 80 and 395 lower than 870. Therefore, our halfway between answer of 475 above is correct.
