Halfway Between 12 and 420

When you ask "What number is halfway between 12 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=12 and Y=420.

Halfway Between Line

To find the number halfway between 12 and 420, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 420 into our formula, we get:

(12 + 420)/2 = 216

Thus, the number halfway between 12 and 420 is 216.

To check that our answer is correct, we subtract 12 from 216 and subtract 216 from 420 and compare the two numbers:

216 - 12 = 204
420 - 216 = 204

As you can see, the halfway number is 204 higher than 12 and 204 lower than 420. Therefore, our halfway between answer of 216 above is correct.
