Halfway Between 78 and 500

When you ask "What number is halfway between 78 and 500?" 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=500.

Halfway Between Line

To find the number halfway between 78 and 500, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 500 into our formula, we get:

(78 + 500)/2 = 289

Thus, the number halfway between 78 and 500 is 289.

To check that our answer is correct, we subtract 78 from 289 and subtract 289 from 500 and compare the two numbers:

289 - 78 = 211
500 - 289 = 211

As you can see, the halfway number is 211 higher than 78 and 211 lower than 500. Therefore, our halfway between answer of 289 above is correct.
