Halfway Between 45 and 320

When you ask "What number is halfway between 45 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=45 and Y=320.

Halfway Between Line

To find the number halfway between 45 and 320, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 320 into our formula, we get:

(45 + 320)/2 = 182.5

Thus, the number halfway between 45 and 320 is 182.5.

To check that our answer is correct, we subtract 45 from 182.5 and subtract 182.5 from 320 and compare the two numbers:

182.5 - 45 = 137.5
320 - 182.5 = 137.5

As you can see, the halfway number is 137.5 higher than 45 and 137.5 lower than 320. Therefore, our halfway between answer of 182.5 above is correct.
