Halfway Between 85 and 630

When you ask "What number is halfway between 85 and 630?" 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=630.

Halfway Between Line

To find the number halfway between 85 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 630 into our formula, we get:

(85 + 630)/2 = 357.5

Thus, the number halfway between 85 and 630 is 357.5.

To check that our answer is correct, we subtract 85 from 357.5 and subtract 357.5 from 630 and compare the two numbers:

357.5 - 85 = 272.5
630 - 357.5 = 272.5

As you can see, the halfway number is 272.5 higher than 85 and 272.5 lower than 630. Therefore, our halfway between answer of 357.5 above is correct.
