Halfway Between 40 and 660

When you ask "What number is halfway between 40 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=40 and Y=660.

Halfway Between Line

To find the number halfway between 40 and 660, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 660 into our formula, we get:

(40 + 660)/2 = 350

Thus, the number halfway between 40 and 660 is 350.

To check that our answer is correct, we subtract 40 from 350 and subtract 350 from 660 and compare the two numbers:

350 - 40 = 310
660 - 350 = 310

As you can see, the halfway number is 310 higher than 40 and 310 lower than 660. Therefore, our halfway between answer of 350 above is correct.
