Halfway Between 30 and 770

When you ask "What number is halfway between 30 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=30 and Y=770.

Halfway Between Line

To find the number halfway between 30 and 770, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 770 into our formula, we get:

(30 + 770)/2 = 400

Thus, the number halfway between 30 and 770 is 400.

To check that our answer is correct, we subtract 30 from 400 and subtract 400 from 770 and compare the two numbers:

400 - 30 = 370
770 - 400 = 370

As you can see, the halfway number is 370 higher than 30 and 370 lower than 770. Therefore, our halfway between answer of 400 above is correct.
