Halfway Between 55 and 637

When you ask "What number is halfway between 55 and 637?" 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=637.

Halfway Between Line

To find the number halfway between 55 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 637 into our formula, we get:

(55 + 637)/2 = 346

Thus, the number halfway between 55 and 637 is 346.

To check that our answer is correct, we subtract 55 from 346 and subtract 346 from 637 and compare the two numbers:

346 - 55 = 291
637 - 346 = 291

As you can see, the halfway number is 291 higher than 55 and 291 lower than 637. Therefore, our halfway between answer of 346 above is correct.
