Halfway Between 55 and 455

When you ask "What number is halfway between 55 and 455?" 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=455.

Halfway Between Line

To find the number halfway between 55 and 455, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 455 into our formula, we get:

(55 + 455)/2 = 255

Thus, the number halfway between 55 and 455 is 255.

To check that our answer is correct, we subtract 55 from 255 and subtract 255 from 455 and compare the two numbers:

255 - 55 = 200
455 - 255 = 200

As you can see, the halfway number is 200 higher than 55 and 200 lower than 455. Therefore, our halfway between answer of 255 above is correct.
