Halfway Between 80 and 830

When you ask "What number is halfway between 80 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=80 and Y=830.

Halfway Between Line

To find the number halfway between 80 and 830, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 830 into our formula, we get:

(80 + 830)/2 = 455

Thus, the number halfway between 80 and 830 is 455.

To check that our answer is correct, we subtract 80 from 455 and subtract 455 from 830 and compare the two numbers:

455 - 80 = 375
830 - 455 = 375

As you can see, the halfway number is 375 higher than 80 and 375 lower than 830. Therefore, our halfway between answer of 455 above is correct.
