Find the wrong term of the series and which number should replace it to make the sequence correct: 24, 34, 36, 51, 48, 68, 60, 85, 70, 102.
Explanation:
Alternate terms form 2 different series.
34, 51, 68, 85, 102 is an AP with common difference of 17
24, 36, 48, 60, 70 is an AP with common difference of 12. In this series instead of 70, 72 should have been there.
Hence, option (a).
