Halfway Between 35 and 645

When you ask "What number is halfway between 35 and 645?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=35 and Y=645.

Halfway Between Line

To find the number halfway between 35 and 645, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 35 and 645 into our formula, we get:

(35 + 645)/2 = 340

Thus, the number halfway between 35 and 645 is 340.

To check that our answer is correct, we subtract 35 from 340 and subtract 340 from 645 and compare the two numbers:

340 - 35 = 305
645 - 340 = 305

As you can see, the halfway number is 305 higher than 35 and 305 lower than 645. Therefore, our halfway between answer of 340 above is correct.
