Halfway Between 40 and 635

When you ask "What number is halfway between 40 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=40 and Y=635.

Halfway Between Line

To find the number halfway between 40 and 635, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 635 into our formula, we get:

(40 + 635)/2 = 337.5

Thus, the number halfway between 40 and 635 is 337.5.

To check that our answer is correct, we subtract 40 from 337.5 and subtract 337.5 from 635 and compare the two numbers:

337.5 - 40 = 297.5
635 - 337.5 = 297.5

As you can see, the halfway number is 297.5 higher than 40 and 297.5 lower than 635. Therefore, our halfway between answer of 337.5 above is correct.
