Halfway Between 10 and 625

When you ask "What number is halfway between 10 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=10 and Y=625.

Halfway Between Line

To find the number halfway between 10 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 625 into our formula, we get:

(10 + 625)/2 = 317.5

Thus, the number halfway between 10 and 625 is 317.5.

To check that our answer is correct, we subtract 10 from 317.5 and subtract 317.5 from 625 and compare the two numbers:

317.5 - 10 = 307.5
625 - 317.5 = 307.5

As you can see, the halfway number is 307.5 higher than 10 and 307.5 lower than 625. Therefore, our halfway between answer of 317.5 above is correct.
