      In each of the following questions, one number in the

      series does not follow the pattern of the others. Identify that wrong number in the series. 7, 11, 17, 25, 36, 47, 61
      A 61 Correct Answer Incorrect Answer
      B 11 Correct Answer Incorrect Answer
      C 7 Correct Answer Incorrect Answer
      D 36 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ, Look at the differences: 11 − 7 = 4 17 − 11 = 6 25 − 17 = 8 36 − 25 = 11 47 − 36 = 11 61 − 47 = 14 If the pattern were: +4, +6, +8, +10, +12, +14 (i.e. differences increasing by 2), then: 7 → 11 (+4) 11 → 17 (+6) 17 → 25 (+8) 25 → 35 (+10) 35 → 47 (+12) 47 → 61 (+14) So the term 36 should be 35. Hence, 36 is the wrong number.
