When you ask "What number is halfway between 47 and 291?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=47 and Y=291.

To find the number halfway between 47 and 291, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 47 and 291 into our formula, we get:
(47 + 291)/2 = 169
Thus, the number halfway between 47 and 291 is 169.
To check that our answer is correct, we subtract 47 from 169 and subtract 169 from 291 and compare the two numbers:
169 - 47 = 122
291 - 169 = 122
As you can see, the halfway number is 122 higher than 47 and 122 lower than 291. Therefore, our halfway between answer of 169 above is correct.
