Halfway Between 85 and 425

When you ask "What number is halfway between 85 and 425?" 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=425.

Halfway Between Line

To find the number halfway between 85 and 425, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 425 into our formula, we get:

(85 + 425)/2 = 255

Thus, the number halfway between 85 and 425 is 255.

To check that our answer is correct, we subtract 85 from 255 and subtract 255 from 425 and compare the two numbers:

255 - 85 = 170
425 - 255 = 170

As you can see, the halfway number is 170 higher than 85 and 170 lower than 425. Therefore, our halfway between answer of 255 above is correct.
