Halfway Between 80 and 660

When you ask "What number is halfway between 80 and 660?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=660.

Halfway Between Line

To find the number halfway between 80 and 660, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 660 into our formula, we get:

(80 + 660)/2 = 370

Thus, the number halfway between 80 and 660 is 370.

To check that our answer is correct, we subtract 80 from 370 and subtract 370 from 660 and compare the two numbers:

370 - 80 = 290
660 - 370 = 290

As you can see, the halfway number is 290 higher than 80 and 290 lower than 660. Therefore, our halfway between answer of 370 above is correct.
