Halfway Between 17 and 635

When you ask "What number is halfway between 17 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=17 and Y=635.

Halfway Between Line

To find the number halfway between 17 and 635, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 635 into our formula, we get:

(17 + 635)/2 = 326

Thus, the number halfway between 17 and 635 is 326.

To check that our answer is correct, we subtract 17 from 326 and subtract 326 from 635 and compare the two numbers:

326 - 17 = 309
635 - 326 = 309

As you can see, the halfway number is 309 higher than 17 and 309 lower than 635. Therefore, our halfway between answer of 326 above is correct.
