Halfway Between 80 and 505

When you ask "What number is halfway between 80 and 505?" 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=505.

Halfway Between Line

To find the number halfway between 80 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 505 into our formula, we get:

(80 + 505)/2 = 292.5

Thus, the number halfway between 80 and 505 is 292.5.

To check that our answer is correct, we subtract 80 from 292.5 and subtract 292.5 from 505 and compare the two numbers:

292.5 - 80 = 212.5
505 - 292.5 = 212.5

As you can see, the halfway number is 212.5 higher than 80 and 212.5 lower than 505. Therefore, our halfway between answer of 292.5 above is correct.
