Halfway Between 13 and 320

When you ask "What number is halfway between 13 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=13 and Y=320.

Halfway Between Line

To find the number halfway between 13 and 320, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 320 into our formula, we get:

(13 + 320)/2 = 166.5

Thus, the number halfway between 13 and 320 is 166.5.

To check that our answer is correct, we subtract 13 from 166.5 and subtract 166.5 from 320 and compare the two numbers:

166.5 - 13 = 153.5
320 - 166.5 = 153.5

As you can see, the halfway number is 153.5 higher than 13 and 153.5 lower than 320. Therefore, our halfway between answer of 166.5 above is correct.
