Halfway Between 20 and 799

When you ask "What number is halfway between 20 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=20 and Y=799.

Halfway Between Line

To find the number halfway between 20 and 799, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 799 into our formula, we get:

(20 + 799)/2 = 409.5

Thus, the number halfway between 20 and 799 is 409.5.

To check that our answer is correct, we subtract 20 from 409.5 and subtract 409.5 from 799 and compare the two numbers:

409.5 - 20 = 389.5
799 - 409.5 = 389.5

As you can see, the halfway number is 389.5 higher than 20 and 389.5 lower than 799. Therefore, our halfway between answer of 409.5 above is correct.
