Halfway Between 21 and 600

When you ask "What number is halfway between 21 and 600?" 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=600.

Halfway Between Line

To find the number halfway between 21 and 600, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 600 into our formula, we get:

(21 + 600)/2 = 310.5

Thus, the number halfway between 21 and 600 is 310.5.

To check that our answer is correct, we subtract 21 from 310.5 and subtract 310.5 from 600 and compare the two numbers:

310.5 - 21 = 289.5
600 - 310.5 = 289.5

As you can see, the halfway number is 289.5 higher than 21 and 289.5 lower than 600. Therefore, our halfway between answer of 310.5 above is correct.
