Halfway Between 13 and 830

When you ask "What number is halfway between 13 and 830?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=830.

Halfway Between Line

To find the number halfway between 13 and 830, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 830 into our formula, we get:

(13 + 830)/2 = 421.5

Thus, the number halfway between 13 and 830 is 421.5.

To check that our answer is correct, we subtract 13 from 421.5 and subtract 421.5 from 830 and compare the two numbers:

421.5 - 13 = 408.5
830 - 421.5 = 408.5

As you can see, the halfway number is 408.5 higher than 13 and 408.5 lower than 830. Therefore, our halfway between answer of 421.5 above is correct.
