Halfway Between 55 and 699

When you ask "What number is halfway between 55 and 699?" 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=699.

Halfway Between Line

To find the number halfway between 55 and 699, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 699 into our formula, we get:

(55 + 699)/2 = 377

Thus, the number halfway between 55 and 699 is 377.

To check that our answer is correct, we subtract 55 from 377 and subtract 377 from 699 and compare the two numbers:

377 - 55 = 322
699 - 377 = 322

As you can see, the halfway number is 322 higher than 55 and 322 lower than 699. Therefore, our halfway between answer of 377 above is correct.
