look at what is added (in parentheses)\n\n2 (+1) 3 (+2) 5 (+0) 5 (+3) 8 (-1) 7 (+4) 11\n\nStarting with the first and taking every other number you have +1 +0 -1.  The other values are +2 +3 +4.  So you have two patterns interwoven.  Following those patterns will yield:\n\n2, 3, 5, 5, 8, 7, 11, 9, 14, 11, 17, 13, 20

The answer is 4.\n11 is eleven, which has 6 letters, so the next number is 6.\n6 is six, which has 3 letters, so the next number is 3.\n3 is three, which has 5 letters, so the next number is 5.\n5 is five, which has 4 letters, so the next number is 4.\n4 is four, which has 4 letters, so the next number is 4. It's all 4's from there!\n\nBy the way, 4 is the only number that has the same number of letters as its value, and if you start this sequence at any whole number, you will end up at four! Just a tidbit I knew! ^_^
