When you ask "What number is halfway between 21 and 625?" 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=625.
To find the number halfway between 21 and 625, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 625 into our formula, we get:
(21 + 625)/2 = 323
Thus, the number halfway between 21 and 625 is 323.
To check that our answer is correct, we subtract 21 from 323 and subtract 323 from 625 and compare the two numbers:
323 - 21 = 302
625 - 323 = 302
As you can see, the halfway number is 302 higher than 21 and 302 lower than 625. Therefore, our halfway between answer of 323 above is correct.
