Halfway Between 20 and 673

When you ask "What number is halfway between 20 and 673?" 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=673.

Halfway Between Line

To find the number halfway between 20 and 673, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 673 into our formula, we get:

(20 + 673)/2 = 346.5

Thus, the number halfway between 20 and 673 is 346.5.

To check that our answer is correct, we subtract 20 from 346.5 and subtract 346.5 from 673 and compare the two numbers:

346.5 - 20 = 326.5
673 - 346.5 = 326.5

As you can see, the halfway number is 326.5 higher than 20 and 326.5 lower than 673. Therefore, our halfway between answer of 346.5 above is correct.
