Halfway Between 17 and 637

When you ask "What number is halfway between 17 and 637?" 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=637.

Halfway Between Line

To find the number halfway between 17 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 637 into our formula, we get:

(17 + 637)/2 = 327

Thus, the number halfway between 17 and 637 is 327.

To check that our answer is correct, we subtract 17 from 327 and subtract 327 from 637 and compare the two numbers:

327 - 17 = 310
637 - 327 = 310

As you can see, the halfway number is 310 higher than 17 and 310 lower than 637. Therefore, our halfway between answer of 327 above is correct.
