Halfway Between 20 and 1000

When you ask "What number is halfway between 20 and 1000?" 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=1000.

Halfway Between Line

To find the number halfway between 20 and 1000, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 1000 into our formula, we get:

(20 + 1000)/2 = 510

Thus, the number halfway between 20 and 1000 is 510.

To check that our answer is correct, we subtract 20 from 510 and subtract 510 from 1000 and compare the two numbers:

510 - 20 = 490
1000 - 510 = 490

As you can see, the halfway number is 490 higher than 20 and 490 lower than 1000. Therefore, our halfway between answer of 510 above is correct.
