Halfway Between 40 and 398

When you ask "What number is halfway between 40 and 398?" 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=398.

Halfway Between Line

To find the number halfway between 40 and 398, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 398 into our formula, we get:

(40 + 398)/2 = 219

Thus, the number halfway between 40 and 398 is 219.

To check that our answer is correct, we subtract 40 from 219 and subtract 219 from 398 and compare the two numbers:

219 - 40 = 179
398 - 219 = 179

As you can see, the halfway number is 179 higher than 40 and 179 lower than 398. Therefore, our halfway between answer of 219 above is correct.
