Halfway Between 17 and 800

When you ask "What number is halfway between 17 and 800?" 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=800.

Halfway Between Line

To find the number halfway between 17 and 800, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 800 into our formula, we get:

(17 + 800)/2 = 408.5

Thus, the number halfway between 17 and 800 is 408.5.

To check that our answer is correct, we subtract 17 from 408.5 and subtract 408.5 from 800 and compare the two numbers:

408.5 - 17 = 391.5
800 - 408.5 = 391.5

As you can see, the halfway number is 391.5 higher than 17 and 391.5 lower than 800. Therefore, our halfway between answer of 408.5 above is correct.
