Halfway Between 78 and 542

When you ask "What number is halfway between 78 and 542?" 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=542.

Halfway Between Line

To find the number halfway between 78 and 542, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 542 into our formula, we get:

(78 + 542)/2 = 310

Thus, the number halfway between 78 and 542 is 310.

To check that our answer is correct, we subtract 78 from 310 and subtract 310 from 542 and compare the two numbers:

310 - 78 = 232
542 - 310 = 232

As you can see, the halfway number is 232 higher than 78 and 232 lower than 542. Therefore, our halfway between answer of 310 above is correct.
