Halfway Between 85 and 717

When you ask "What number is halfway between 85 and 717?" 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=717.

Halfway Between Line

To find the number halfway between 85 and 717, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 717 into our formula, we get:

(85 + 717)/2 = 401

Thus, the number halfway between 85 and 717 is 401.

To check that our answer is correct, we subtract 85 from 401 and subtract 401 from 717 and compare the two numbers:

401 - 85 = 316
717 - 401 = 316

As you can see, the halfway number is 316 higher than 85 and 316 lower than 717. Therefore, our halfway between answer of 401 above is correct.
