Halfway Between 43 and 820

When you ask "What number is halfway between 43 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=43 and Y=820.

Halfway Between Line

To find the number halfway between 43 and 820, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 820 into our formula, we get:

(43 + 820)/2 = 431.5

Thus, the number halfway between 43 and 820 is 431.5.

To check that our answer is correct, we subtract 43 from 431.5 and subtract 431.5 from 820 and compare the two numbers:

431.5 - 43 = 388.5
820 - 431.5 = 388.5

As you can see, the halfway number is 388.5 higher than 43 and 388.5 lower than 820. Therefore, our halfway between answer of 431.5 above is correct.
