Halfway Between 90 and 485

When you ask "What number is halfway between 90 and 485?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=485.

Halfway Between Line

To find the number halfway between 90 and 485, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 485 into our formula, we get:

(90 + 485)/2 = 287.5

Thus, the number halfway between 90 and 485 is 287.5.

To check that our answer is correct, we subtract 90 from 287.5 and subtract 287.5 from 485 and compare the two numbers:

287.5 - 90 = 197.5
485 - 287.5 = 197.5

As you can see, the halfway number is 197.5 higher than 90 and 197.5 lower than 485. Therefore, our halfway between answer of 287.5 above is correct.
