Halfway Between 17 and 455

When you ask "What number is halfway between 17 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=17 and Y=455.

Halfway Between Line

To find the number halfway between 17 and 455, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 455 into our formula, we get:

(17 + 455)/2 = 236

Thus, the number halfway between 17 and 455 is 236.

To check that our answer is correct, we subtract 17 from 236 and subtract 236 from 455 and compare the two numbers:

236 - 17 = 219
455 - 236 = 219

As you can see, the halfway number is 219 higher than 17 and 219 lower than 455. Therefore, our halfway between answer of 236 above is correct.
