the sum of all the numbers / the number of the numbers

you would get only one unknown to find.

I'm not given the other 3 numbers. I think I'm misinterpreting what you are saying sum/amount of numbers or sum/each number totaled up. 22/4=5.5 evenly distributed. I'm also running into an issue also one of the numbers doesn't necessarily have to be 8 the 4 numbers average is 8.

oh wait 3 of 4 numbers have a sum of eight. 6,7,, and 9=22 so the 4th number has to be 8. but 22/3=7.3 I mean visually it makes sense but mathematically I'm not getting the answer.

Would that be (22+x)/4=8 ok I got 10. Thanks. I just had to think a bit more straighter. :)

I don't know, I think I work better by writing down equations or just writing everything down.
