Halfway Between 80 and 818

When you ask "What number is halfway between 80 and 818?" 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=818.

Halfway Between Line

To find the number halfway between 80 and 818, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 818 into our formula, we get:

(80 + 818)/2 = 449

Thus, the number halfway between 80 and 818 is 449.

To check that our answer is correct, we subtract 80 from 449 and subtract 449 from 818 and compare the two numbers:

449 - 80 = 369
818 - 449 = 369

As you can see, the halfway number is 369 higher than 80 and 369 lower than 818. Therefore, our halfway between answer of 449 above is correct.
