Halfway Between 15 and 219

When you ask "What number is halfway between 15 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=15 and Y=219.

Halfway Between Line

To find the number halfway between 15 and 219, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 219 into our formula, we get:

(15 + 219)/2 = 117

Thus, the number halfway between 15 and 219 is 117.

To check that our answer is correct, we subtract 15 from 117 and subtract 117 from 219 and compare the two numbers:

117 - 15 = 102
219 - 117 = 102

As you can see, the halfway number is 102 higher than 15 and 102 lower than 219. Therefore, our halfway between answer of 117 above is correct.
