Halfway Between 25 and 647

When you ask "What number is halfway between 25 and 647?" 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=647.

Halfway Between Line

To find the number halfway between 25 and 647, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 647 into our formula, we get:

(25 + 647)/2 = 336

Thus, the number halfway between 25 and 647 is 336.

To check that our answer is correct, we subtract 25 from 336 and subtract 336 from 647 and compare the two numbers:

336 - 25 = 311
647 - 336 = 311

As you can see, the halfway number is 311 higher than 25 and 311 lower than 647. Therefore, our halfway between answer of 336 above is correct.
