Hi Shamil Could it be a 5-based sequence? (10)5 (11)5 (12)5 (13)5 (14)5 (20)5 (22)5 (?)5 (31)5 equals in 10-base: 5 6 7 8 9 10 12 (?) 16 Then number that fits in here is 14, thus the missing item in 5-base is 24. /gustav >>> shamil at users.mns.ru 23-09-2005 15:27 >>> P.S. My Friday puzzle to you Gustav :) What is the missing number: 10 11 12 13 14 20 22 (?) 31
