The numbers above have been arranged according to a certain rule. What is the value of the missing number x?

I think this has been posted before but annoyingly I cannot remember the answer :)

Yes, and some of us played silly games and dropped cryptic clues.

But my tortuous answer needs more posts.

I didn't realise this had been posted previously. But it is a marvellous puzzle and I urge all to try for a solution without following UncleEbenezer's link. I will give full attribution with the solution. I tend not to give the source with the problem as it is a temptation to google for an answer.

I agree, it's a fine puzzle, with that splendid red herring to distract you from an answer that should be more obvious.

I suspect the lack of takers here may be because those of us who might bite remember it from first time round. Or already knew it back then. For myself, I don't think I can improve on my convoluted post number [solution] in that thread.

Thank you for that remark. Got me looking at it differently. The required rule then became quite obvious quite quickly.

I had completely forgotten that I had posted this. I have just worked it out - nothing too complicated.
