Halfway Between 85 and 490

When you ask "What number is halfway between 85 and 490?" 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=490.

Halfway Between Line

To find the number halfway between 85 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 490 into our formula, we get:

(85 + 490)/2 = 287.5

Thus, the number halfway between 85 and 490 is 287.5.

To check that our answer is correct, we subtract 85 from 287.5 and subtract 287.5 from 490 and compare the two numbers:

287.5 - 85 = 202.5
490 - 287.5 = 202.5

As you can see, the halfway number is 202.5 higher than 85 and 202.5 lower than 490. Therefore, our halfway between answer of 287.5 above is correct.
