Halfway Between 100 and 799

When you ask "What number is halfway between 100 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=100 and Y=799.

Halfway Between Line

To find the number halfway between 100 and 799, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 799 into our formula, we get:

(100 + 799)/2 = 449.5

Thus, the number halfway between 100 and 799 is 449.5.

To check that our answer is correct, we subtract 100 from 449.5 and subtract 449.5 from 799 and compare the two numbers:

449.5 - 100 = 349.5
799 - 449.5 = 349.5

As you can see, the halfway number is 349.5 higher than 100 and 349.5 lower than 799. Therefore, our halfway between answer of 449.5 above is correct.
