Halfway Between 45 and 316

When you ask "What number is halfway between 45 and 316?" 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=316.

Halfway Between Line

To find the number halfway between 45 and 316, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 316 into our formula, we get:

(45 + 316)/2 = 180.5

Thus, the number halfway between 45 and 316 is 180.5.

To check that our answer is correct, we subtract 45 from 180.5 and subtract 180.5 from 316 and compare the two numbers:

180.5 - 45 = 135.5
316 - 180.5 = 135.5

As you can see, the halfway number is 135.5 higher than 45 and 135.5 lower than 316. Therefore, our halfway between answer of 180.5 above is correct.
