Halfway Between 15 and 427

When you ask "What number is halfway between 15 and 427?" 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=427.

Halfway Between Line

To find the number halfway between 15 and 427, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 427 into our formula, we get:

(15 + 427)/2 = 221

Thus, the number halfway between 15 and 427 is 221.

To check that our answer is correct, we subtract 15 from 221 and subtract 221 from 427 and compare the two numbers:

221 - 15 = 206
427 - 221 = 206

As you can see, the halfway number is 206 higher than 15 and 206 lower than 427. Therefore, our halfway between answer of 221 above is correct.
