Halfway Between 30 and 800

When you ask "What number is halfway between 30 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=30 and Y=800.

Halfway Between Line

To find the number halfway between 30 and 800, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 800 into our formula, we get:

(30 + 800)/2 = 415

Thus, the number halfway between 30 and 800 is 415.

To check that our answer is correct, we subtract 30 from 415 and subtract 415 from 800 and compare the two numbers:

415 - 30 = 385
800 - 415 = 385

As you can see, the halfway number is 385 higher than 30 and 385 lower than 800. Therefore, our halfway between answer of 415 above is correct.
