Halfway Between 80 and 823

When you ask "What number is halfway between 80 and 823?" 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=823.

Halfway Between Line

To find the number halfway between 80 and 823, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 823 into our formula, we get:

(80 + 823)/2 = 451.5

Thus, the number halfway between 80 and 823 is 451.5.

To check that our answer is correct, we subtract 80 from 451.5 and subtract 451.5 from 823 and compare the two numbers:

451.5 - 80 = 371.5
823 - 451.5 = 371.5

As you can see, the halfway number is 371.5 higher than 80 and 371.5 lower than 823. Therefore, our halfway between answer of 451.5 above is correct.
