Halfway Between 22 and 820

When you ask "What number is halfway between 22 and 820?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=22 and Y=820.

Halfway Between Line

To find the number halfway between 22 and 820, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 22 and 820 into our formula, we get:

(22 + 820)/2 = 421

Thus, the number halfway between 22 and 820 is 421.

To check that our answer is correct, we subtract 22 from 421 and subtract 421 from 820 and compare the two numbers:

421 - 22 = 399
820 - 421 = 399

As you can see, the halfway number is 399 higher than 22 and 399 lower than 820. Therefore, our halfway between answer of 421 above is correct.
