Halfway Between 29 and 817

When you ask "What number is halfway between 29 and 817?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=29 and Y=817.

Halfway Between Line

To find the number halfway between 29 and 817, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 29 and 817 into our formula, we get:

(29 + 817)/2 = 423

Thus, the number halfway between 29 and 817 is 423.

To check that our answer is correct, we subtract 29 from 423 and subtract 423 from 817 and compare the two numbers:

423 - 29 = 394
817 - 423 = 394

As you can see, the halfway number is 394 higher than 29 and 394 lower than 817. Therefore, our halfway between answer of 423 above is correct.
