Halfway Between 78 and 445

When you ask "What number is halfway between 78 and 445?" 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=445.

Halfway Between Line

To find the number halfway between 78 and 445, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 445 into our formula, we get:

(78 + 445)/2 = 261.5

Thus, the number halfway between 78 and 445 is 261.5.

To check that our answer is correct, we subtract 78 from 261.5 and subtract 261.5 from 445 and compare the two numbers:

261.5 - 78 = 183.5
445 - 261.5 = 183.5

As you can see, the halfway number is 183.5 higher than 78 and 183.5 lower than 445. Therefore, our halfway between answer of 261.5 above is correct.
