Halfway Between 55 and 655

When you ask "What number is halfway between 55 and 655?" 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=655.

Halfway Between Line

To find the number halfway between 55 and 655, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 655 into our formula, we get:

(55 + 655)/2 = 355

Thus, the number halfway between 55 and 655 is 355.

To check that our answer is correct, we subtract 55 from 355 and subtract 355 from 655 and compare the two numbers:

355 - 55 = 300
655 - 355 = 300

As you can see, the halfway number is 300 higher than 55 and 300 lower than 655. Therefore, our halfway between answer of 355 above is correct.
