Halfway Between 85 and 517

When you ask "What number is halfway between 85 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=85 and Y=517.

Halfway Between Line

To find the number halfway between 85 and 517, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 517 into our formula, we get:

(85 + 517)/2 = 301

Thus, the number halfway between 85 and 517 is 301.

To check that our answer is correct, we subtract 85 from 301 and subtract 301 from 517 and compare the two numbers:

301 - 85 = 216
517 - 301 = 216

As you can see, the halfway number is 216 higher than 85 and 216 lower than 517. Therefore, our halfway between answer of 301 above is correct.
