It was: 2 3 10 12 13 20 21 22 . . . (What is the next number?) I got a flock of correct answers (23, all the numbers that begin with the letter "t") and I want to thank you all. Instead of kicking myself in the head (difficult to do) for not having figured it out, I retaliated by making up some series problems for him. He did well, got all but two of them (in time). How can you do? In each case, what is the next number of the series, AND WHY! 31 28 31 4 9 7 6 10 3 8 15 20 20 6 6 19 19 7 8 5 5 3 4 4 2 4 6 8 12 14 18 20 24 1 5 10 25 50 1 4 1 5 1 1 1 2 3 5 11 26 Good puzzling, I will post answers later. -- Tom Butler ..!ihnp4!ihuxn!ttb
