Halfway Between 17 and 623

When you ask "What number is halfway between 17 and 623?" 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=623.

Halfway Between Line

To find the number halfway between 17 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 623 into our formula, we get:

(17 + 623)/2 = 320

Thus, the number halfway between 17 and 623 is 320.

To check that our answer is correct, we subtract 17 from 320 and subtract 320 from 623 and compare the two numbers:

320 - 17 = 303
623 - 320 = 303

As you can see, the halfway number is 303 higher than 17 and 303 lower than 623. Therefore, our halfway between answer of 320 above is correct.
