Halfway Between 78 and 497

When you ask "What number is halfway between 78 and 497?" 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=497.

Halfway Between Line

To find the number halfway between 78 and 497, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 497 into our formula, we get:

(78 + 497)/2 = 287.5

Thus, the number halfway between 78 and 497 is 287.5.

To check that our answer is correct, we subtract 78 from 287.5 and subtract 287.5 from 497 and compare the two numbers:

287.5 - 78 = 209.5
497 - 287.5 = 209.5

As you can see, the halfway number is 209.5 higher than 78 and 209.5 lower than 497. Therefore, our halfway between answer of 287.5 above is correct.
