Halfway Between 78 and 770

When you ask "What number is halfway between 78 and 770?" 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=770.

Halfway Between Line

To find the number halfway between 78 and 770, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 770 into our formula, we get:

(78 + 770)/2 = 424

Thus, the number halfway between 78 and 770 is 424.

To check that our answer is correct, we subtract 78 from 424 and subtract 424 from 770 and compare the two numbers:

424 - 78 = 346
770 - 424 = 346

As you can see, the halfway number is 346 higher than 78 and 346 lower than 770. Therefore, our halfway between answer of 424 above is correct.
