  1. m00li added an answer to a question Hard number sequence: 4, 8, 16, 26, 41, 57, 79, 104, 138, 184, 241, ?   

    Let S1=(n-2)(n-3)(n-4)(n-5)(n-6)(n-7)(n-8)(n-9)(n-10)(n-11)
    S2=(n-1)(n-3)(n-4)(n-5)(n-6)(n-7)(n-8)(n-9)(n-10)(n-11)
    S3=(n-1)(n-2)(n-4)(n-5)(n-6)(n-7)(n-8)(n-9)(n-10)(n-11)
    so on till
    S11=(n-1)(n-2)(n-3)(n-4)(n-5)(n-6)(n-7)(n-8)(n-9)(n-10)
    where n is any natural number

    then the sequence is given by

    (4/3628800)S1 -(8/362880)S2 +(16/80640)S3 -(26/30240)S4 +(41/17280)S5 -(57/14400)S6 +(79/17280)S7 -(104/30240)S8 +(138/80640)S9 -(184/362880)S10 +(241/3628800)S11

    Yes Bonanova, I did not permit zeros as I thought in that case Rainman would have given a different initial reply (that he can never find out Y-San's product)

    Rip-off
    Fifty school children lined up at random in five rows and ten columns.
    No two of the children have the same birthday.
    What is the probability that
    the youngest child among the oldest children in each column is
    NOT older than
    the oldest child among the youngest children in each row ?

    Since, Rainman knows the product, he doesn't even have to think about the other number. This doesn't change the fact that there are indeed two answers to your problem.
    Or, am I wrong in stating that there are two possible answers to your question?
