    challenge !

    recently i was reading up on crytpography and general encoding etc and stumbled across a little challenge ! it took me 2 hours to work it out, is anyone here quicker ??? i am sure there is !

    2,4,6
    30,32,34,36
    40,42,44,46
    50,52,54,56
    60,62,64,66

    What is the next sequence of numbers and why ?

    happy deciphering peeps !

    uuuuuuuum........this is the simple way, probably wrong, but 70, 72, 74, 76, cuz at the beginning, there's {0 understood}, 02, 04, 06, then x0, x2, x4, x6, so than could be a logical answer

    sorry miles away but good attempt all the same, i went through all logic processes and quite a few tantrums before i got there !

    70, 72,74, 76 cause the key is the first sequence and each column is read top to bottom, and what is a peep? Time spent 1 minute.

    if the key was the first sequence then the first sequence would be 0,2,4,6 but its not !
    it is 2,4,6

    think laterally and along the lines of cryptography,encoding etc !111111

    Humm see .3 then .6 and the first number 2 always goes in = to the next in the sequence. Funny thing then again is my view on the code, maybe more then one answer, time spent 30 seconds, just pattern matching is all

    but then is it ?

    Just to change the subject slightly I found a challenge myself.
    The challenge is attached.
    If you don't want to know the answer, look away now!

    Each three letter combination, eg 120, is split up into the template of 16,4,1 like binary only with these number.
    16 | 4 | 1
    ------------
    1 | 2 | 0 = 24.

    So that letter is the 24th letter of the alphabet.

    Other than pattern matching... hmm

    end of line + 4
    else +2 would generate the following results
    When number adds a place, add number to sequence

    2,4,6
    10,12,14,16
    20,22,24,26
    30,32,34,36
    40,42,44,46
    50,52,54,56
    60,62,64,66
    70,72,74,76

    10 100 110

    11110 100000 100010 100100
    101000 101010 101100 101110
    110010 110100 110110 111000
    111100 111110 1000000 1000010
    1000110 1001000 1001010 1001100

    patterns noticed: in 2's column the on switch rotates each row in eavery set.

    Other than that... you've got me. I can't wait to learn the secret
