Halfway Between 30 and 799

When you ask "What number is halfway between 30 and 799?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=799.

Halfway Between Line

To find the number halfway between 30 and 799, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 799 into our formula, we get:

(30 + 799)/2 = 414.5

Thus, the number halfway between 30 and 799 is 414.5.

To check that our answer is correct, we subtract 30 from 414.5 and subtract 414.5 from 799 and compare the two numbers:

414.5 - 30 = 384.5
799 - 414.5 = 384.5

As you can see, the halfway number is 384.5 higher than 30 and 384.5 lower than 799. Therefore, our halfway between answer of 414.5 above is correct.
