Halfway Between 45 and 625

When you ask "What number is halfway between 45 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=45 and Y=625.

Halfway Between Line

To find the number halfway between 45 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 625 into our formula, we get:

(45 + 625)/2 = 335

Thus, the number halfway between 45 and 625 is 335.

To check that our answer is correct, we subtract 45 from 335 and subtract 335 from 625 and compare the two numbers:

335 - 45 = 290
625 - 335 = 290

As you can see, the halfway number is 290 higher than 45 and 290 lower than 625. Therefore, our halfway between answer of 335 above is correct.
