  • Question

  • 5, 4, 9, 18, 66, 195


  • Options
  • A. 12
  • B. 25
  • C. 20
  • D. 18

  • Correct Answer
  • 18 

    Explanation

    This series is made of two position series .
    Even Position series :-
    ? First term = 5
    Second term = ( First term × 1 ) - 1
    ? Second term = ( 5 × 1 ) - 1 = 4
    Fourth term = ( Third term × 2 ) - 2
    ? Fourth term = ( 9 × 2 ) - 2 = 18 , 16 should be Fourth term because ( 9 × 2 ) - 2 = 16 .
    So 18 is wrong. we get 16 as Fourth term.
    Sixth term = ( Fifth term × 3 ) - 3
    ? Sixth term = ( 66 × 3 ) - 3 = 195
    Odd Position series -
    ? Second term = 4
    Third term = ( Second term × 2 ) + 2
    ? Third term = ( 4 × 2 ) + 2 = 10
    Fifth term = ( Fourth term × 3 ) + 3
    ? Fifth term = ( 16 × 3 ) + 3 = 51
