Halfway Between 31 and 320

When you ask "What number is halfway between 31 and 320?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=31 and Y=320.

Halfway Between Line

To find the number halfway between 31 and 320, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 320 into our formula, we get:

(31 + 320)/2 = 175.5

Thus, the number halfway between 31 and 320 is 175.5.

To check that our answer is correct, we subtract 31 from 175.5 and subtract 175.5 from 320 and compare the two numbers:

175.5 - 31 = 144.5
320 - 175.5 = 144.5

As you can see, the halfway number is 144.5 higher than 31 and 144.5 lower than 320. Therefore, our halfway between answer of 175.5 above is correct.
