Halfway Between 43 and 403

When you ask "What number is halfway between 43 and 403?" 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=403.

Halfway Between Line

To find the number halfway between 43 and 403, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 403 into our formula, we get:

(43 + 403)/2 = 223

Thus, the number halfway between 43 and 403 is 223.

To check that our answer is correct, we subtract 43 from 223 and subtract 223 from 403 and compare the two numbers:

223 - 43 = 180
403 - 223 = 180

As you can see, the halfway number is 180 higher than 43 and 180 lower than 403. Therefore, our halfway between answer of 223 above is correct.
