Halfway Between 20 and 742

When you ask "What number is halfway between 20 and 742?" 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=742.

Halfway Between Line

To find the number halfway between 20 and 742, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 742 into our formula, we get:

(20 + 742)/2 = 381

Thus, the number halfway between 20 and 742 is 381.

To check that our answer is correct, we subtract 20 from 381 and subtract 381 from 742 and compare the two numbers:

381 - 20 = 361
742 - 381 = 361

As you can see, the halfway number is 361 higher than 20 and 361 lower than 742. Therefore, our halfway between answer of 381 above is correct.
