Halfway Between 45 and 200

When you ask "What number is halfway between 45 and 200?" 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=200.

Halfway Between Line

To find the number halfway between 45 and 200, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 200 into our formula, we get:

(45 + 200)/2 = 122.5

Thus, the number halfway between 45 and 200 is 122.5.

To check that our answer is correct, we subtract 45 from 122.5 and subtract 122.5 from 200 and compare the two numbers:

122.5 - 45 = 77.5
200 - 122.5 = 77.5

As you can see, the halfway number is 77.5 higher than 45 and 77.5 lower than 200. Therefore, our halfway between answer of 122.5 above is correct.
