Halfway Between 85 and 455

When you ask "What number is halfway between 85 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=85 and Y=455.

Halfway Between Line

To find the number halfway between 85 and 455, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 455 into our formula, we get:

(85 + 455)/2 = 270

Thus, the number halfway between 85 and 455 is 270.

To check that our answer is correct, we subtract 85 from 270 and subtract 270 from 455 and compare the two numbers:

270 - 85 = 185
455 - 270 = 185

As you can see, the halfway number is 185 higher than 85 and 185 lower than 455. Therefore, our halfway between answer of 270 above is correct.
