  • Question
  • 2 , 8 ,32 , 148 , 765 , 4626 , 32431


  • Options
  • A. 765
  • B. 148
  • C. 8
  • D. 32

  • Correct Answer
  • 32 

    Explanation

    From the given graph , we can see that the increasing order of series as -
    First term = 2
    Second term = First term × 2 + 22
    ? Second term = 2 × 2 + 22 = 4 + 4 = 8 ;
    Third term = Second term × 3 + 32
    ? Third term = 8 × 3 + 32 = 24 + 9 = 32 ; 32 is wrong. It should be 33.
    Similarly , we can find all others terms also.
    Fourth term = Third term × 4 + 42
    ? Fourth term = 33 × 4 + 42 = 132 + 16 = 148 ;
    Fifth term = Fourth term × 5 + 52
    ? Fifth term = 148 × 5 + 52 = 740 + 25 = 765 ;
    Sixth term = Fifth term × 6 + 62
    ? Sixth term = 765 × 6 + 62 = 4590 + 36 = 4626 ;
    Seventh term = Sixth term × 7 + 72
    ? Seventh term = 4626 × 7 + 72 = 32382 + 49 = 32431
    Hence, 32 is wrong. It should be 33.
