Halfway Between 40 and 420

When you ask "What number is halfway between 40 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=40 and Y=420.

Halfway Between Line

To find the number halfway between 40 and 420, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 420 into our formula, we get:

(40 + 420)/2 = 230

Thus, the number halfway between 40 and 420 is 230.

To check that our answer is correct, we subtract 40 from 230 and subtract 230 from 420 and compare the two numbers:

230 - 40 = 190
420 - 230 = 190

As you can see, the halfway number is 190 higher than 40 and 190 lower than 420. Therefore, our halfway between answer of 230 above is correct.
