Halfway Between 17 and 425

When you ask "What number is halfway between 17 and 425?" 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=425.

Halfway Between Line

To find the number halfway between 17 and 425, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 425 into our formula, we get:

(17 + 425)/2 = 221

Thus, the number halfway between 17 and 425 is 221.

To check that our answer is correct, we subtract 17 from 221 and subtract 221 from 425 and compare the two numbers:

221 - 17 = 204
425 - 221 = 204

As you can see, the halfway number is 204 higher than 17 and 204 lower than 425. Therefore, our halfway between answer of 221 above is correct.
