  • Question

  • 1, 2, 4.5, 11, 30, 92.5, 329


  • Options
  • A. 92.5
  • B. 4.5
  • C. 11
  • D. 2

  • Correct Answer
  • 92.5 

    Explanation

    As per the details in the question the series is in the form of
    First term = 1
    Second term = ( First term × Variable ) + Variable = 2
    Third term = ( Second term × Previous Variable + 0.5 ) + Previous Variable + 0.5 = 4.5
    Similarly we can find the all others terms
    Second term = ( 1 × 1 ) + 1 = 2
    Third term = ( 2 × 1.5 ) + 1.5 = 4.5
    Fourth term = ( 4.5 × 2 ) + 2 = 11
    Fifth term = (11 × 2.5 ) + 2.5 = 30
    Sixth term = ( 30 × 3 ) + 3 = 92.5 , 93 should be sixth term because ( 30 × 3 ) + 3 = 93
    So 92.5 is wrong. we get 93 as 6th term.
    Seventh term = ( 93 × 3.5 ) + 3.5 = 325.5 + 3.5 = 329.
