Halfway Between 11 and 625

When you ask "What number is halfway between 11 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=11 and Y=625.

Halfway Between Line

To find the number halfway between 11 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 625 into our formula, we get:

(11 + 625)/2 = 318

Thus, the number halfway between 11 and 625 is 318.

To check that our answer is correct, we subtract 11 from 318 and subtract 318 from 625 and compare the two numbers:

318 - 11 = 307
625 - 318 = 307

As you can see, the halfway number is 307 higher than 11 and 307 lower than 625. Therefore, our halfway between answer of 318 above is correct.
