Halfway Between 78 and 502

When you ask "What number is halfway between 78 and 502?" 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=502.

Halfway Between Line

To find the number halfway between 78 and 502, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 502 into our formula, we get:

(78 + 502)/2 = 290

Thus, the number halfway between 78 and 502 is 290.

To check that our answer is correct, we subtract 78 from 290 and subtract 290 from 502 and compare the two numbers:

290 - 78 = 212
502 - 290 = 212

As you can see, the halfway number is 212 higher than 78 and 212 lower than 502. Therefore, our halfway between answer of 290 above is correct.
