  • B. 75

  • D. 15

  • Correct Answer
  • 167.5 

    Explanation

    The given series is in the below pattern,
    First term = 3
    Second term = First term × 2.5
    ? Second term = 3 × 2.5 = 7.5 ;
    Third term = Second term × 2
    ? Third term = 7.5 × 2 = 15 ;
    Fourth term = Third term × 2.5
    ? Fourth term = 15 × 2.5 = 37.5 ;
    Fifth term = Fourth term × 2
    ? Fifth term = 37.5 × 2 = 75 ;
    Sixth term = Fifth term × 2.5
    ? Sixth term = 75 × 2.5 = 167.5; 167.5 is wrong. It should be 187.5.
    Seventh term = Sixth term × 2
    ? Seventh term = 187.5 × 2 = 375 ;
    Hence, 167.5 is wrong. It should be 187.5.
