When you ask "What number is halfway between 69 and 557?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=69 and Y=557.
To find the number halfway between 69 and 557, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 69 and 557 into our formula, we get:
(69 + 557)/2 = 313
Thus, the number halfway between 69 and 557 is 313.
To check that our answer is correct, we subtract 69 from 313 and subtract 313 from 557 and compare the two numbers:
313 - 69 = 244
557 - 313 = 244
As you can see, the halfway number is 244 higher than 69 and 244 lower than 557. Therefore, our halfway between answer of 313 above is correct.
