    It is enciphered using the rule
    R (m)=m (mod 91)

    The resulting ciphertext is ( 73,14,23,73,23)
    Verify the rule given satisfy the condition for an RSA cipher.

    Using the repeated squaring technique decipher the ciphertext and find the message

    Use mathematical induction to prove that
    E 1/r(r+1)(r+2)=n(n+3)/4(n+1)(n+2) for n+1,2,3,.......
