Halfway Between 29 and 839

When you ask "What number is halfway between 29 and 839?" 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=839.

Halfway Between Line

To find the number halfway between 29 and 839, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 29 and 839 into our formula, we get:

(29 + 839)/2 = 434

Thus, the number halfway between 29 and 839 is 434.

To check that our answer is correct, we subtract 29 from 434 and subtract 434 from 839 and compare the two numbers:

434 - 29 = 405
839 - 434 = 405

As you can see, the halfway number is 405 higher than 29 and 405 lower than 839. Therefore, our halfway between answer of 434 above is correct.
