Halfway Between 42 and 728

When you ask "What number is halfway between 42 and 728?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=42 and Y=728.

Halfway Between Line

To find the number halfway between 42 and 728, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 728 into our formula, we get:

(42 + 728)/2 = 385

Thus, the number halfway between 42 and 728 is 385.

To check that our answer is correct, we subtract 42 from 385 and subtract 385 from 728 and compare the two numbers:

385 - 42 = 343
728 - 385 = 343

As you can see, the halfway number is 343 higher than 42 and 343 lower than 728. Therefore, our halfway between answer of 385 above is correct.
