Halfway Between 55 and 305

When you ask "What number is halfway between 55 and 305?" 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=305.

Halfway Between Line

To find the number halfway between 55 and 305, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 305 into our formula, we get:

(55 + 305)/2 = 180

Thus, the number halfway between 55 and 305 is 180.

To check that our answer is correct, we subtract 55 from 180 and subtract 180 from 305 and compare the two numbers:

180 - 55 = 125
305 - 180 = 125

As you can see, the halfway number is 125 higher than 55 and 125 lower than 305. Therefore, our halfway between answer of 180 above is correct.
