Halfway Between 78 and 612

When you ask "What number is halfway between 78 and 612?" 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=612.

Halfway Between Line

To find the number halfway between 78 and 612, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 612 into our formula, we get:

(78 + 612)/2 = 345

Thus, the number halfway between 78 and 612 is 345.

To check that our answer is correct, we subtract 78 from 345 and subtract 345 from 612 and compare the two numbers:

345 - 78 = 267
612 - 345 = 267

As you can see, the halfway number is 267 higher than 78 and 267 lower than 612. Therefore, our halfway between answer of 345 above is correct.
