Halfway Between 55 and 355

When you ask "What number is halfway between 55 and 355?" 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=355.

Halfway Between Line

To find the number halfway between 55 and 355, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 355 into our formula, we get:

(55 + 355)/2 = 205

Thus, the number halfway between 55 and 355 is 205.

To check that our answer is correct, we subtract 55 from 205 and subtract 205 from 355 and compare the two numbers:

205 - 55 = 150
355 - 205 = 150

As you can see, the halfway number is 150 higher than 55 and 150 lower than 355. Therefore, our halfway between answer of 205 above is correct.
