Halfway Between 10 and 55

When you ask "What number is halfway between 10 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=10 and Y=55.

Halfway Between Line

To find the number halfway between 10 and 55, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 55 into our formula, we get:

(10 + 55)/2 = 32.5

Thus, the number halfway between 10 and 55 is 32.5.

To check that our answer is correct, we subtract 10 from 32.5 and subtract 32.5 from 55 and compare the two numbers:

32.5 - 10 = 22.5
55 - 32.5 = 22.5

As you can see, the halfway number is 22.5 higher than 10 and 22.5 lower than 55. Therefore, our halfway between answer of 32.5 above is correct.
