Halfway Between 55 and 680

When you ask "What number is halfway between 55 and 680?" 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=680.

Halfway Between Line

To find the number halfway between 55 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 680 into our formula, we get:

(55 + 680)/2 = 367.5

Thus, the number halfway between 55 and 680 is 367.5.

To check that our answer is correct, we subtract 55 from 367.5 and subtract 367.5 from 680 and compare the two numbers:

367.5 - 55 = 312.5
680 - 367.5 = 312.5

As you can see, the halfway number is 312.5 higher than 55 and 312.5 lower than 680. Therefore, our halfway between answer of 367.5 above is correct.
