Halfway Between 80 and 517

When you ask "What number is halfway between 80 and 517?" 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=517.

Halfway Between Line

To find the number halfway between 80 and 517, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 517 into our formula, we get:

(80 + 517)/2 = 298.5

Thus, the number halfway between 80 and 517 is 298.5.

To check that our answer is correct, we subtract 80 from 298.5 and subtract 298.5 from 517 and compare the two numbers:

298.5 - 80 = 218.5
517 - 298.5 = 218.5

As you can see, the halfway number is 218.5 higher than 80 and 218.5 lower than 517. Therefore, our halfway between answer of 298.5 above is correct.
