Halfway Between 1 and 635

When you ask "What number is halfway between 1 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=1 and Y=635.

Halfway Between Line

To find the number halfway between 1 and 635, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 635 into our formula, we get:

(1 + 635)/2 = 318

Thus, the number halfway between 1 and 635 is 318.

To check that our answer is correct, we subtract 1 from 318 and subtract 318 from 635 and compare the two numbers:

318 - 1 = 317
635 - 318 = 317

As you can see, the halfway number is 317 higher than 1 and 317 lower than 635. Therefore, our halfway between answer of 318 above is correct.
