    Here are the answers to the number puzzles. Thanks to all who answered them with a special thanks to Stephen Riddle who answered the one I could not.

      Here are the answers to the number puzzles. Thanks to all who answered them with
      a special thanks to Stephen Riddle who answered the one I could not.
       
       
      12321   23432  34543  45654  56765  ?     the number is 67876
      start with one then up -up -down- down  then start with two, repeat pattern
      Another answer is to add 11111 to the numbers - better answer than mine.
       
      3692-4    216874-6   32-2   26915-5   9-1   6857392-?
      the number is 7 -  number after dash is count of numbers before the dash
       
      12  2  23  3  34  ?   the number is 4
      start with 12 then repeat the two put 3 after 2 then repeat the 3 put 4 after 3 and then  repeat the 4
       
      Another answer is that it is two interwoven sequences:
      (1) start with 12 and add 11 to get to the third answer, 5th is 11 mote than 3rd, etc.
      (2) 2nd, 4th, 6th, etc. are just 2 3 4 etc
      .
      312-4   8-2   15-4   351-1   242-2   216-?
      the number is 3,   The number after the dash is the remainder after
      subtracting the sum of the numbers before the dash from 10 
       
      This is the one I could not see the pattern for. Thanks to Steven Riddle who figured it out. I thought there were some people out there who were smart enough to find the answer and I was right about that. 
       
      326-1957   732-6195   573-2619   957-3261   195-7326   the number is 619-5732
      put last number in front and move the dash to maintain the pattern.  
       
      I knew the answers to to 1, 2, 3 and 5 when I posed them, but did not know the answer to
      number 4.

      Here are the answers to the number puzzles. Oh oh! This is an old pasttime -- guessing what rule MIGHT underlie the construction of a sequence of numbers.

        "Here are the answers to the number puzzles."

        Oh oh! This is an old pasttime -- guessing what rule MIGHT underlie the construction of a sequence of numbers.

        The question is almost always phrased incorrectly. "What is the next term in the sequence" makes no sense. The question is "What may be the rule that defines this sequence and what is THEN the next term". Any mathematician or any logical thinker will tell you that THERE IS NO CORRECT NEXT TERM until the sequence has been defined.

        Visit the On-Line Encyclopedia of Integer Sequences - http://www.research.att.com/~njas/sequences/ ! Enter your sequence 12321 23432 34543 45654 56765 . You will find that your sequence 12321 23432 34543 45654 56765 is (or better, happens to be) a sub-sequence of the Giza-sequence. The next two members are indeed 67876 and 78987, each formed by adding 111111 to the previous member. But there it ends.

        Remember: THERE IS NO CORRECT NEXT TERM of a sequence until the sequence has been defined.

        "Here are the answers to the number puzzles." means only "Here are possible answers to the number puzzles."

        Here is one I first heard 30 years ago. A-B-C-D-E-F-G-H-I-J-K-L-M-N-O-P-Q-R-S-T-U-V-W-X-Y-Z Line:1 A-E-F-H-I-K-L-M-N-T-? Line:2 B-C-D-G-J-O-P-Q-R-S-? As Bruce

          Here is one I first heard 30 years ago.

          A-B-C-D-E-F-G-H-I-J-K-L-M-N-O-P-Q-R-S-T-U-V-W-X-Y-Z

          Line:1 A-E-F-H-I-K-L-M-N-T-?
          Line:2 B-C-D-G-J-O-P-Q-R-S-?

          As Bruce Summers would put it "what rule MIGHT underlie the construction
          of the sequence" and what are the next and following letters on each row.

          Note: It was given with the hint that my five year old brother might
          solve it faster than I could.
