I am puzzled? I have just worked out the sequence and about to post it but why, crofter, are you not prepared to reveal the logig? Should I withhold it as well?
gen2 No good reason except to let others enjoy getting there! The setters of such problems often know the answer anyway. I wasn't trying to be obstructive or devious. I did intend to come back to the posting and give the logic if it was still unanswered.
In fact, the question has been answered with the 6 given.
The logic comes from counting the letters in the following ZERO ONE TWO THREE ... TEN (ELEVEN)
By the way gen2 I DID appreciate your input this weekend in the Links Game - Thanks
That's OK crofter. I wondered if you knew this was from some special quiz or other and that revealing too much was taboo - like the Rainbow quizzes that people here get so possessive about. I couldnt do Quball15 's code puzzle so will sleep on it. Night all.
