When you ask "What number is halfway between 85 and 769?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=85 and Y=769.

To find the number halfway between 85 and 769, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 85 and 769 into our formula, we get:
(85 + 769)/2 = 427
Thus, the number halfway between 85 and 769 is 427.
To check that our answer is correct, we subtract 85 from 427 and subtract 427 from 769 and compare the two numbers:
427 - 85 = 342
769 - 427 = 342
As you can see, the halfway number is 342 higher than 85 and 342 lower than 769. Therefore, our halfway between answer of 427 above is correct.
