Halfway Between 15 and 415

When you ask "What number is halfway between 15 and 415?" 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=415.

Halfway Between Line

To find the number halfway between 15 and 415, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 415 into our formula, we get:

(15 + 415)/2 = 215

Thus, the number halfway between 15 and 415 is 215.

To check that our answer is correct, we subtract 15 from 215 and subtract 215 from 415 and compare the two numbers:

215 - 15 = 200
415 - 215 = 200

As you can see, the halfway number is 200 higher than 15 and 200 lower than 415. Therefore, our halfway between answer of 215 above is correct.
