Halfway Between 17 and 631

When you ask "What number is halfway between 17 and 631?" 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=631.

Halfway Between Line

To find the number halfway between 17 and 631, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 631 into our formula, we get:

(17 + 631)/2 = 324

Thus, the number halfway between 17 and 631 is 324.

To check that our answer is correct, we subtract 17 from 324 and subtract 324 from 631 and compare the two numbers:

324 - 17 = 307
631 - 324 = 307

As you can see, the halfway number is 307 higher than 17 and 307 lower than 631. Therefore, our halfway between answer of 324 above is correct.
