      Find the wrong number in the given number series.

      10, 21, 14, 25, 18, 30
      A 30 Correct Answer Incorrect Answer
      B 10 Correct Answer Incorrect Answer
      C 21 Correct Answer Incorrect Answer
      D 14 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      10 + 11 = 21

      21 – 7 = 14

      14 + 11 = 25

      25 – 7 = 18

      18 + 11 = 29

      So, 29 should come in place of 30.
