Halfway Between 55 and 616

When you ask "What number is halfway between 55 and 616?" 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=616.

Halfway Between Line

To find the number halfway between 55 and 616, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 616 into our formula, we get:

(55 + 616)/2 = 335.5

Thus, the number halfway between 55 and 616 is 335.5.

To check that our answer is correct, we subtract 55 from 335.5 and subtract 335.5 from 616 and compare the two numbers:

335.5 - 55 = 280.5
616 - 335.5 = 280.5

As you can see, the halfway number is 280.5 higher than 55 and 280.5 lower than 616. Therefore, our halfway between answer of 335.5 above is correct.
