Halfway Between 80 and 455

When you ask "What number is halfway between 80 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=80 and Y=455.

Halfway Between Line

To find the number halfway between 80 and 455, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 455 into our formula, we get:

(80 + 455)/2 = 267.5

Thus, the number halfway between 80 and 455 is 267.5.

To check that our answer is correct, we subtract 80 from 267.5 and subtract 267.5 from 455 and compare the two numbers:

267.5 - 80 = 187.5
455 - 267.5 = 187.5

As you can see, the halfway number is 187.5 higher than 80 and 187.5 lower than 455. Therefore, our halfway between answer of 267.5 above is correct.
