Halfway Between 45 and 574

When you ask "What number is halfway between 45 and 574?" 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=574.

Halfway Between Line

To find the number halfway between 45 and 574, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 574 into our formula, we get:

(45 + 574)/2 = 309.5

Thus, the number halfway between 45 and 574 is 309.5.

To check that our answer is correct, we subtract 45 from 309.5 and subtract 309.5 from 574 and compare the two numbers:

309.5 - 45 = 264.5
574 - 309.5 = 264.5

As you can see, the halfway number is 264.5 higher than 45 and 264.5 lower than 574. Therefore, our halfway between answer of 309.5 above is correct.
