Halfway Between 85 and 625

When you ask "What number is halfway between 85 and 625?" 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=625.

Halfway Between Line

To find the number halfway between 85 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 625 into our formula, we get:

(85 + 625)/2 = 355

Thus, the number halfway between 85 and 625 is 355.

To check that our answer is correct, we subtract 85 from 355 and subtract 355 from 625 and compare the two numbers:

355 - 85 = 270
625 - 355 = 270

As you can see, the halfway number is 270 higher than 85 and 270 lower than 625. Therefore, our halfway between answer of 355 above is correct.
