Halfway Between 55 and 516

When you ask "What number is halfway between 55 and 516?" 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=516.

Halfway Between Line

To find the number halfway between 55 and 516, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 516 into our formula, we get:

(55 + 516)/2 = 285.5

Thus, the number halfway between 55 and 516 is 285.5.

To check that our answer is correct, we subtract 55 from 285.5 and subtract 285.5 from 516 and compare the two numbers:

285.5 - 55 = 230.5
516 - 285.5 = 230.5

As you can see, the halfway number is 230.5 higher than 55 and 230.5 lower than 516. Therefore, our halfway between answer of 285.5 above is correct.
