Halfway Between 88 and 870

When you ask "What number is halfway between 88 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=88 and Y=870.

Halfway Between Line

To find the number halfway between 88 and 870, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 870 into our formula, we get:

(88 + 870)/2 = 479

Thus, the number halfway between 88 and 870 is 479.

To check that our answer is correct, we subtract 88 from 479 and subtract 479 from 870 and compare the two numbers:

479 - 88 = 391
870 - 479 = 391

As you can see, the halfway number is 391 higher than 88 and 391 lower than 870. Therefore, our halfway between answer of 479 above is correct.
