Halfway Between 55 and 788

When you ask "What number is halfway between 55 and 788?" 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=788.

Halfway Between Line

To find the number halfway between 55 and 788, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 788 into our formula, we get:

(55 + 788)/2 = 421.5

Thus, the number halfway between 55 and 788 is 421.5.

To check that our answer is correct, we subtract 55 from 421.5 and subtract 421.5 from 788 and compare the two numbers:

421.5 - 55 = 366.5
788 - 421.5 = 366.5

As you can see, the halfway number is 366.5 higher than 55 and 366.5 lower than 788. Therefore, our halfway between answer of 421.5 above is correct.
