Halfway Between 30 and 830

When you ask "What number is halfway between 30 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=30 and Y=830.

Halfway Between Line

To find the number halfway between 30 and 830, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 830 into our formula, we get:

(30 + 830)/2 = 430

Thus, the number halfway between 30 and 830 is 430.

To check that our answer is correct, we subtract 30 from 430 and subtract 430 from 830 and compare the two numbers:

430 - 30 = 400
830 - 430 = 400

As you can see, the halfway number is 400 higher than 30 and 400 lower than 830. Therefore, our halfway between answer of 430 above is correct.
