Halfway Between 70 and 680

When you ask "What number is halfway between 70 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=70 and Y=680.

Halfway Between Line

To find the number halfway between 70 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 680 into our formula, we get:

(70 + 680)/2 = 375

Thus, the number halfway between 70 and 680 is 375.

To check that our answer is correct, we subtract 70 from 375 and subtract 375 from 680 and compare the two numbers:

375 - 70 = 305
680 - 375 = 305

As you can see, the halfway number is 305 higher than 70 and 305 lower than 680. Therefore, our halfway between answer of 375 above is correct.
