Halfway Between 55 and 770

When you ask "What number is halfway between 55 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=55 and Y=770.

Halfway Between Line

To find the number halfway between 55 and 770, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 770 into our formula, we get:

(55 + 770)/2 = 412.5

Thus, the number halfway between 55 and 770 is 412.5.

To check that our answer is correct, we subtract 55 from 412.5 and subtract 412.5 from 770 and compare the two numbers:

412.5 - 55 = 357.5
770 - 412.5 = 357.5

As you can see, the halfway number is 357.5 higher than 55 and 357.5 lower than 770. Therefore, our halfway between answer of 412.5 above is correct.
