Halfway Between 85 and 529

When you ask "What number is halfway between 85 and 529?" 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=529.

Halfway Between Line

To find the number halfway between 85 and 529, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 529 into our formula, we get:

(85 + 529)/2 = 307

Thus, the number halfway between 85 and 529 is 307.

To check that our answer is correct, we subtract 85 from 307 and subtract 307 from 529 and compare the two numbers:

307 - 85 = 222
529 - 307 = 222

As you can see, the halfway number is 222 higher than 85 and 222 lower than 529. Therefore, our halfway between answer of 307 above is correct.
