Halfway Between 4 and 55

When you ask "What number is halfway between 4 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=4 and Y=55.

Halfway Between Line

To find the number halfway between 4 and 55, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 55 into our formula, we get:

(4 + 55)/2 = 29.5

Thus, the number halfway between 4 and 55 is 29.5.

To check that our answer is correct, we subtract 4 from 29.5 and subtract 29.5 from 55 and compare the two numbers:

29.5 - 4 = 25.5
55 - 29.5 = 25.5

As you can see, the halfway number is 25.5 higher than 4 and 25.5 lower than 55. Therefore, our halfway between answer of 29.5 above is correct.
