Halfway Between 80 and 817

When you ask "What number is halfway between 80 and 817?" 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=817.

Halfway Between Line

To find the number halfway between 80 and 817, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 817 into our formula, we get:

(80 + 817)/2 = 448.5

Thus, the number halfway between 80 and 817 is 448.5.

To check that our answer is correct, we subtract 80 from 448.5 and subtract 448.5 from 817 and compare the two numbers:

448.5 - 80 = 368.5
817 - 448.5 = 368.5

As you can see, the halfway number is 368.5 higher than 80 and 368.5 lower than 817. Therefore, our halfway between answer of 448.5 above is correct.
