Correct answer: B
Correct Answer: Option B (141)
Explanation:
Look at the gaps between consecutive terms. Each gap is 9 more than the previous gap: 11, 20, 29, 38, 47.
7 + 11 = 18
18 + 20 = 38
38 + 29 = 67
67 + 38 = 105
105 + 47 = 152
The sixth term should therefore be 152, but the series shows 141. So 141 is the incorrect number.
