  • Question
  • 2, 13, 65, 271, 817, 1639, 1645


  • Options
  • A. 13
  • B. 65
  • C. 271
  • D. 817

  • Correct Answer
  • 65 

    Explanation

    The given series is in the below pattern,
    ? First term = 2
    Second term = ( First term × 6 ) + 1 = 13
    Third term = ( Second term × 5 ) + 2 = 65 , 67 should be sixth term because ( 13 × 5 ) + 2 = 67 .
    So 65 is wrong. we get 67 as Third term.
    Similarly we can find the all terms
    Fourth term = ( Third term × 4 ) + 3 = 271
    Fifth term = ( Fourth term × 3 ) + 2 = 817
    Sixth term = 1639,
    Seventh term = 1645.
