Halfway Between 15 and 209

When you ask "What number is halfway between 15 and 209?" 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=209.

Halfway Between Line

To find the number halfway between 15 and 209, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 209 into our formula, we get:

(15 + 209)/2 = 112

Thus, the number halfway between 15 and 209 is 112.

To check that our answer is correct, we subtract 15 from 112 and subtract 112 from 209 and compare the two numbers:

112 - 15 = 97
209 - 112 = 97

As you can see, the halfway number is 97 higher than 15 and 97 lower than 209. Therefore, our halfway between answer of 112 above is correct.
