Halfway Between 55 and 617

When you ask "What number is halfway between 55 and 617?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=617.

Halfway Between Line

To find the number halfway between 55 and 617, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 617 into our formula, we get:

(55 + 617)/2 = 336

Thus, the number halfway between 55 and 617 is 336.

To check that our answer is correct, we subtract 55 from 336 and subtract 336 from 617 and compare the two numbers:

336 - 55 = 281
617 - 336 = 281

As you can see, the halfway number is 281 higher than 55 and 281 lower than 617. Therefore, our halfway between answer of 336 above is correct.
