Halfway Between 78 and 501

When you ask "What number is halfway between 78 and 501?" 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=501.

Halfway Between Line

To find the number halfway between 78 and 501, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 501 into our formula, we get:

(78 + 501)/2 = 289.5

Thus, the number halfway between 78 and 501 is 289.5.

To check that our answer is correct, we subtract 78 from 289.5 and subtract 289.5 from 501 and compare the two numbers:

289.5 - 78 = 211.5
501 - 289.5 = 211.5

As you can see, the halfway number is 211.5 higher than 78 and 211.5 lower than 501. Therefore, our halfway between answer of 289.5 above is correct.
