Halfway Between 0 and 420

When you ask "What number is halfway between 0 and 420?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=420.

Halfway Between Line

To find the number halfway between 0 and 420, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 420 into our formula, we get:

(0 + 420)/2 = 210

Thus, the number halfway between 0 and 420 is 210.

To check that our answer is correct, we subtract 0 from 210 and subtract 210 from 420 and compare the two numbers:

210 - 0 = 210
420 - 210 = 210

As you can see, the halfway number is 210 higher than 0 and 210 lower than 420. Therefore, our halfway between answer of 210 above is correct.
