Step 1: Understanding the Concept:
Identify the pattern in the sequence.
Step 2: Detailed Explanation:
The sequence alternates between decreasing and increasing. Alternatively, consider pairs: (1,4) difference 3, (2,3) difference 1, (2,?) difference -? Another pattern: 1 to 4 (+3), 4 to 2 (-2), 2 to 3 (+1), 3 to 2 (-1). The next should be (+0) or follow pattern of increments: +3, -2, +1, -1, then +0 gives
2. So ? = 2.
Step 3: Final Answer:
The next number is 2.
