Halfway Between 20 and 656

When you ask "What number is halfway between 20 and 656?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=656.

Halfway Between Line

To find the number halfway between 20 and 656, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 656 into our formula, we get:

(20 + 656)/2 = 338

Thus, the number halfway between 20 and 656 is 338.

To check that our answer is correct, we subtract 20 from 338 and subtract 338 from 656 and compare the two numbers:

338 - 20 = 318
656 - 338 = 318

As you can see, the halfway number is 318 higher than 20 and 318 lower than 656. Therefore, our halfway between answer of 338 above is correct.
