Halfway Between 17 and 551

When you ask "What number is halfway between 17 and 551?" 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=551.

Halfway Between Line

To find the number halfway between 17 and 551, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 551 into our formula, we get:

(17 + 551)/2 = 284

Thus, the number halfway between 17 and 551 is 284.

To check that our answer is correct, we subtract 17 from 284 and subtract 284 from 551 and compare the two numbers:

284 - 17 = 267
551 - 284 = 267

As you can see, the halfway number is 267 higher than 17 and 267 lower than 551. Therefore, our halfway between answer of 284 above is correct.
