Halfway Between 55 and 219

When you ask "What number is halfway between 55 and 219?" 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=219.

Halfway Between Line

To find the number halfway between 55 and 219, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 219 into our formula, we get:

(55 + 219)/2 = 137

Thus, the number halfway between 55 and 219 is 137.

To check that our answer is correct, we subtract 55 from 137 and subtract 137 from 219 and compare the two numbers:

137 - 55 = 82
219 - 137 = 82

As you can see, the halfway number is 82 higher than 55 and 82 lower than 219. Therefore, our halfway between answer of 137 above is correct.
