Halfway Between 90 and 635

When you ask "What number is halfway between 90 and 635?" 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=635.

Halfway Between Line

To find the number halfway between 90 and 635, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 635 into our formula, we get:

(90 + 635)/2 = 362.5

Thus, the number halfway between 90 and 635 is 362.5.

To check that our answer is correct, we subtract 90 from 362.5 and subtract 362.5 from 635 and compare the two numbers:

362.5 - 90 = 272.5
635 - 362.5 = 272.5

As you can see, the halfway number is 272.5 higher than 90 and 272.5 lower than 635. Therefore, our halfway between answer of 362.5 above is correct.
