Halfway Between 20 and 339

When you ask "What number is halfway between 20 and 339?" 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=339.

Halfway Between Line

To find the number halfway between 20 and 339, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 339 into our formula, we get:

(20 + 339)/2 = 179.5

Thus, the number halfway between 20 and 339 is 179.5.

To check that our answer is correct, we subtract 20 from 179.5 and subtract 179.5 from 339 and compare the two numbers:

179.5 - 20 = 159.5
339 - 179.5 = 159.5

As you can see, the halfway number is 159.5 higher than 20 and 159.5 lower than 339. Therefore, our halfway between answer of 179.5 above is correct.
