Halfway Between 88 and 820

When you ask "What number is halfway between 88 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=88 and Y=820.

Halfway Between Line

To find the number halfway between 88 and 820, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 820 into our formula, we get:

(88 + 820)/2 = 454

Thus, the number halfway between 88 and 820 is 454.

To check that our answer is correct, we subtract 88 from 454 and subtract 454 from 820 and compare the two numbers:

454 - 88 = 366
820 - 454 = 366

As you can see, the halfway number is 366 higher than 88 and 366 lower than 820. Therefore, our halfway between answer of 454 above is correct.
