Halfway Between 25 and 625

When you ask "What number is halfway between 25 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=25 and Y=625.

Halfway Between Line

To find the number halfway between 25 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 625 into our formula, we get:

(25 + 625)/2 = 325

Thus, the number halfway between 25 and 625 is 325.

To check that our answer is correct, we subtract 25 from 325 and subtract 325 from 625 and compare the two numbers:

325 - 25 = 300
625 - 325 = 300

As you can see, the halfway number is 300 higher than 25 and 300 lower than 625. Therefore, our halfway between answer of 325 above is correct.
