Halfway Between 15 and 406

When you ask "What number is halfway between 15 and 406?" 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=406.

Halfway Between Line

To find the number halfway between 15 and 406, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 406 into our formula, we get:

(15 + 406)/2 = 210.5

Thus, the number halfway between 15 and 406 is 210.5.

To check that our answer is correct, we subtract 15 from 210.5 and subtract 210.5 from 406 and compare the two numbers:

210.5 - 15 = 195.5
406 - 210.5 = 195.5

As you can see, the halfway number is 195.5 higher than 15 and 195.5 lower than 406. Therefore, our halfway between answer of 210.5 above is correct.
