Halfway Between 78 and 365

When you ask "What number is halfway between 78 and 365?" 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=365.

Halfway Between Line

To find the number halfway between 78 and 365, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 365 into our formula, we get:

(78 + 365)/2 = 221.5

Thus, the number halfway between 78 and 365 is 221.5.

To check that our answer is correct, we subtract 78 from 221.5 and subtract 221.5 from 365 and compare the two numbers:

221.5 - 78 = 143.5
365 - 221.5 = 143.5

As you can see, the halfway number is 143.5 higher than 78 and 143.5 lower than 365. Therefore, our halfway between answer of 221.5 above is correct.
