Halfway Between 20 and 310

When you ask "What number is halfway between 20 and 310?" 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=310.

Halfway Between Line

To find the number halfway between 20 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 310 into our formula, we get:

(20 + 310)/2 = 165

Thus, the number halfway between 20 and 310 is 165.

To check that our answer is correct, we subtract 20 from 165 and subtract 165 from 310 and compare the two numbers:

165 - 20 = 145
310 - 165 = 145

As you can see, the halfway number is 145 higher than 20 and 145 lower than 310. Therefore, our halfway between answer of 165 above is correct.
