      30, 39, 23, 47, 12, 61
      A 39 Correct Answer Incorrect Answer
      B 47 Correct Answer Incorrect Answer
      C 12 Correct Answer Incorrect Answer
      D 61 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      30 + (3)Β² = 39

      39 - (4)Β² = 23

      23 + (5)Β² = 48

      48 - (6)Β² = 12

      12 + (7)Β² = 61

      So, 48 should be in place of 47.
