Halfway Between 55 and 635

When you ask "What number is halfway between 55 and 635?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=635.

Halfway Between Line

To find the number halfway between 55 and 635, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 635 into our formula, we get:

(55 + 635)/2 = 345

Thus, the number halfway between 55 and 635 is 345.

To check that our answer is correct, we subtract 55 from 345 and subtract 345 from 635 and compare the two numbers:

345 - 55 = 290
635 - 345 = 290

As you can see, the halfway number is 290 higher than 55 and 290 lower than 635. Therefore, our halfway between answer of 345 above is correct.
