Halfway Between 15 and 225

When you ask "What number is halfway between 15 and 225?" 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=225.

Halfway Between Line

To find the number halfway between 15 and 225, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 225 into our formula, we get:

(15 + 225)/2 = 120

Thus, the number halfway between 15 and 225 is 120.

To check that our answer is correct, we subtract 15 from 120 and subtract 120 from 225 and compare the two numbers:

120 - 15 = 105
225 - 120 = 105

As you can see, the halfway number is 105 higher than 15 and 105 lower than 225. Therefore, our halfway between answer of 120 above is correct.
