  • Question

  • 3 10 32 111 460 2315
    2 (a) (b) (c) (d) (e)
    Which of the following numbers will come in place of (b)?


  • Options
  • A. 29
  • B. 30
  • C. 26
  • D. 28

  • Correct Answer
  • 30 

    Explanation

    The given series is in the below pattern ,
    First series :-
    First term = 3
    Second term = First term × 1 + 7 × 1
    ? Second term = 3 × 1 + 7 × 1 = 3 + 7 = 10
    Third term = Second term × 2 + 6 × 2
    ? Third term = 10 × 2 + 6 × 2 = 20 + 12 = 32
    similarly , we can calculate the all next terms .
    Second series :-
    First term = 2
    Second term = First term × 1 + 7 × 1
    ? Second term = 2 × 1 + 7 × 1 = 2 + 7 = 9
    Third term = Second term × 2 + 6 × 2
    ? Third term = 9 × 2 + 6 × 2 = 18 + 12 = 30
    Hence , the place value of ( b ) is 30 .
