Halfway Between 85 and 528

When you ask "What number is halfway between 85 and 528?" 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=528.

Halfway Between Line

To find the number halfway between 85 and 528, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 528 into our formula, we get:

(85 + 528)/2 = 306.5

Thus, the number halfway between 85 and 528 is 306.5.

To check that our answer is correct, we subtract 85 from 306.5 and subtract 306.5 from 528 and compare the two numbers:

306.5 - 85 = 221.5
528 - 306.5 = 221.5

As you can see, the halfway number is 221.5 higher than 85 and 221.5 lower than 528. Therefore, our halfway between answer of 306.5 above is correct.
