Halfway Between 21 and 360

When you ask "What number is halfway between 21 and 360?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=360.

Halfway Between Line

To find the number halfway between 21 and 360, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 360 into our formula, we get:

(21 + 360)/2 = 190.5

Thus, the number halfway between 21 and 360 is 190.5.

To check that our answer is correct, we subtract 21 from 190.5 and subtract 190.5 from 360 and compare the two numbers:

190.5 - 21 = 169.5
360 - 190.5 = 169.5

As you can see, the halfway number is 169.5 higher than 21 and 169.5 lower than 360. Therefore, our halfway between answer of 190.5 above is correct.
