Halfway Between 43 and 398

When you ask "What number is halfway between 43 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=43 and Y=398.

Halfway Between Line

To find the number halfway between 43 and 398, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 398 into our formula, we get:

(43 + 398)/2 = 220.5

Thus, the number halfway between 43 and 398 is 220.5.

To check that our answer is correct, we subtract 43 from 220.5 and subtract 220.5 from 398 and compare the two numbers:

220.5 - 43 = 177.5
398 - 220.5 = 177.5

As you can see, the halfway number is 177.5 higher than 43 and 177.5 lower than 398. Therefore, our halfway between answer of 220.5 above is correct.
