Halfway Between 78 and 616

When you ask "What number is halfway between 78 and 616?" 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=616.

Halfway Between Line

To find the number halfway between 78 and 616, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 616 into our formula, we get:

(78 + 616)/2 = 347

Thus, the number halfway between 78 and 616 is 347.

To check that our answer is correct, we subtract 78 from 347 and subtract 347 from 616 and compare the two numbers:

347 - 78 = 269
616 - 347 = 269

As you can see, the halfway number is 269 higher than 78 and 269 lower than 616. Therefore, our halfway between answer of 347 above is correct.
