Halfway Between 17 and 625

When you ask "What number is halfway between 17 and 625?" 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=625.

Halfway Between Line

To find the number halfway between 17 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 625 into our formula, we get:

(17 + 625)/2 = 321

Thus, the number halfway between 17 and 625 is 321.

To check that our answer is correct, we subtract 17 from 321 and subtract 321 from 625 and compare the two numbers:

321 - 17 = 304
625 - 321 = 304

As you can see, the halfway number is 304 higher than 17 and 304 lower than 625. Therefore, our halfway between answer of 321 above is correct.
