Halfway Between 3 and 398

When you ask "What number is halfway between 3 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=3 and Y=398.

Halfway Between Line

To find the number halfway between 3 and 398, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 398 into our formula, we get:

(3 + 398)/2 = 200.5

Thus, the number halfway between 3 and 398 is 200.5.

To check that our answer is correct, we subtract 3 from 200.5 and subtract 200.5 from 398 and compare the two numbers:

200.5 - 3 = 197.5
398 - 200.5 = 197.5

As you can see, the halfway number is 197.5 higher than 3 and 197.5 lower than 398. Therefore, our halfway between answer of 200.5 above is correct.
