Halfway Between 78 and 493

When you ask "What number is halfway between 78 and 493?" 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=493.

Halfway Between Line

To find the number halfway between 78 and 493, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 493 into our formula, we get:

(78 + 493)/2 = 285.5

Thus, the number halfway between 78 and 493 is 285.5.

To check that our answer is correct, we subtract 78 from 285.5 and subtract 285.5 from 493 and compare the two numbers:

285.5 - 78 = 207.5
493 - 285.5 = 207.5

As you can see, the halfway number is 207.5 higher than 78 and 207.5 lower than 493. Therefore, our halfway between answer of 285.5 above is correct.
