I had to draw boxes and go through the list.

I don't think the 98% is right.

Okay then try this one:-

Find 8 positive unique whole numbers between 1 and 20, inclusive (i.e you can use 1 and 20 if you want to) that contain no arithmetic or geometric progressions between any three terms.

Reminder for those who cant remember that far back:-

An arithmetic progression is a minimum of three numbers where the difference between them is the same eg, 5, 10, 15 where the difference is 5, or 2, 4, 6 where the difference is 2.

A goemetric progression is one where a minimum of three numbers have a common multiplier eg, 2, 4, 8 where the common multiplier is 2 or 2, 6, 18 where the common multiplier is 3.

Remember you cannot have ANY three numbers which from an arithmetic or goemetric progression not just three that are next to each other.

I will post the solution in a couple of days if nobody solves it.

You don't need a computer or calculator to obtain the solution.

Aaahhh......I said I came up with an answer......I guess I omitted to say that it wasn't the correct answer.

The setup alone makes my head hurt. I could die if I tried this.

LOL,

Explaining it without ambiguity is a lot more difficult that actually solving it, you should find this easy after Einsteins puzzle, now that really did do my ed in, I was ok with the houses but the nationalities were tricky and I confess to cheating a bit with those. After that it was plain sailing.

Clue:- All you need is a pencil and paper and be able to count to 20.

C'mon Fetor you know you can do it
