Halfway Between 45 and 455

When you ask "What number is halfway between 45 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=45 and Y=455.

Halfway Between Line

To find the number halfway between 45 and 455, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 455 into our formula, we get:

(45 + 455)/2 = 250

Thus, the number halfway between 45 and 455 is 250.

To check that our answer is correct, we subtract 45 from 250 and subtract 250 from 455 and compare the two numbers:

250 - 45 = 205
455 - 250 = 205

As you can see, the halfway number is 205 higher than 45 and 205 lower than 455. Therefore, our halfway between answer of 250 above is correct.
