Halfway Between 55 and 215

When you ask "What number is halfway between 55 and 215?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=215.

Halfway Between Line

To find the number halfway between 55 and 215, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 215 into our formula, we get:

(55 + 215)/2 = 135

Thus, the number halfway between 55 and 215 is 135.

To check that our answer is correct, we subtract 55 from 135 and subtract 135 from 215 and compare the two numbers:

135 - 55 = 80
215 - 135 = 80

As you can see, the halfway number is 80 higher than 55 and 80 lower than 215. Therefore, our halfway between answer of 135 above is correct.
