Halfway Between 45 and 55

When you ask "What number is halfway between 45 and 55?" 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=55.

Halfway Between Line

To find the number halfway between 45 and 55, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 55 into our formula, we get:

(45 + 55)/2 = 50

Thus, the number halfway between 45 and 55 is 50.

To check that our answer is correct, we subtract 45 from 50 and subtract 50 from 55 and compare the two numbers:

50 - 45 = 5
55 - 50 = 5

As you can see, the halfway number is 5 higher than 45 and 5 lower than 55. Therefore, our halfway between answer of 50 above is correct.
