Halfway Between 55 and 636

When you ask "What number is halfway between 55 and 636?" 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=636.

Halfway Between Line

To find the number halfway between 55 and 636, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 636 into our formula, we get:

(55 + 636)/2 = 345.5

Thus, the number halfway between 55 and 636 is 345.5.

To check that our answer is correct, we subtract 55 from 345.5 and subtract 345.5 from 636 and compare the two numbers:

345.5 - 55 = 290.5
636 - 345.5 = 290.5

As you can see, the halfway number is 290.5 higher than 55 and 290.5 lower than 636. Therefore, our halfway between answer of 345.5 above is correct.
