Halfway Between 15 and 215

When you ask "What number is halfway between 15 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=15 and Y=215.

Halfway Between Line

To find the number halfway between 15 and 215, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 215 into our formula, we get:

(15 + 215)/2 = 115

Thus, the number halfway between 15 and 215 is 115.

To check that our answer is correct, we subtract 15 from 115 and subtract 115 from 215 and compare the two numbers:

115 - 15 = 100
215 - 115 = 100

As you can see, the halfway number is 100 higher than 15 and 100 lower than 215. Therefore, our halfway between answer of 115 above is correct.
