Halfway Between 90 and 285

When you ask "What number is halfway between 90 and 285?" 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=285.

Halfway Between Line

To find the number halfway between 90 and 285, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 285 into our formula, we get:

(90 + 285)/2 = 187.5

Thus, the number halfway between 90 and 285 is 187.5.

To check that our answer is correct, we subtract 90 from 187.5 and subtract 187.5 from 285 and compare the two numbers:

187.5 - 90 = 97.5
285 - 187.5 = 97.5

As you can see, the halfway number is 97.5 higher than 90 and 97.5 lower than 285. Therefore, our halfway between answer of 187.5 above is correct.
