Halfway Between 11 and 635

When you ask "What number is halfway between 11 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=11 and Y=635.

Halfway Between Line

To find the number halfway between 11 and 635, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 635 into our formula, we get:

(11 + 635)/2 = 323

Thus, the number halfway between 11 and 635 is 323.

To check that our answer is correct, we subtract 11 from 323 and subtract 323 from 635 and compare the two numbers:

323 - 11 = 312
635 - 323 = 312

As you can see, the halfway number is 312 higher than 11 and 312 lower than 635. Therefore, our halfway between answer of 323 above is correct.
