Halfway Between 15 and 407

When you ask "What number is halfway between 15 and 407?" 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=407.

Halfway Between Line

To find the number halfway between 15 and 407, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 407 into our formula, we get:

(15 + 407)/2 = 211

Thus, the number halfway between 15 and 407 is 211.

To check that our answer is correct, we subtract 15 from 211 and subtract 211 from 407 and compare the two numbers:

211 - 15 = 196
407 - 211 = 196

As you can see, the halfway number is 196 higher than 15 and 196 lower than 407. Therefore, our halfway between answer of 211 above is correct.
