Number series coding and Decoding and odd man out

Concept:Identify the pattern in the series by analyzing consecutive differences.Explanation:Step 1: Compute differences between consecutive terms:$60 - 24 = 36$$120 - 60 = 60$$210 - 120 = 90$Step 2: The differences form a new series: $36, 60, 90$.Compute their differences: $60 - 36 = 24$, $90 - 60 = 30$Step 3: The second-level differences increase by $6$ each time. Next second-level difference is $30 + 6 = 36$.Thus, next first-level difference = $90 + 36 = 126$.Step 4: Next term = $210 + 126 = 336$.Answer:336
