Halfway Between 45 and 310

When you ask "What number is halfway between 45 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=45 and Y=310.

Halfway Between Line

To find the number halfway between 45 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 310 into our formula, we get:

(45 + 310)/2 = 177.5

Thus, the number halfway between 45 and 310 is 177.5.

To check that our answer is correct, we subtract 45 from 177.5 and subtract 177.5 from 310 and compare the two numbers:

177.5 - 45 = 132.5
310 - 177.5 = 132.5

As you can see, the halfway number is 132.5 higher than 45 and 132.5 lower than 310. Therefore, our halfway between answer of 177.5 above is correct.
