Math Proof

“Solve this equation step-by-step: prove that for all positive integers n, the sum of the first n odd numbers equals n squared. Show full reasoning chain.”

Logic Puzzle

“Three houses in a row, labeled A B C. A has red door, B blue, C green. Owners: Alice baker, Bob coder, Charlie engineer. Baker hates green. Coder in middle. Who lives where? Reason fully.”

Code Debug

“Debug this Python function that fails on large inputs: def factorial(n): if n == 0: return 1 else: return n * factorial(n-1). Identify recursion issue and fix with reasoning.”

Data Analysis

“Analyze sales data: Q1:100 units $10k, Q2:150 $15k, Q3:120 $12k. Predict Q4 trend, suggest actions. Use chain-of-thought for agentic planning.”
