Halfway Between 78 and 904

When you ask "What number is halfway between 78 and 904?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=904.

Halfway Between Line

To find the number halfway between 78 and 904, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 904 into our formula, we get:

(78 + 904)/2 = 491

Thus, the number halfway between 78 and 904 is 491.

To check that our answer is correct, we subtract 78 from 491 and subtract 491 from 904 and compare the two numbers:

491 - 78 = 413
904 - 491 = 413

As you can see, the halfway number is 413 higher than 78 and 413 lower than 904. Therefore, our halfway between answer of 491 above is correct.
