For the following claim and proof: n Claim: For every n € N, Proof: 3⁰ 3-1 = 1, and k+1 Σ3 i=0 3k+1 1 2 - +3k+1 i=0 3n+1 2 3k+1 1 2 + 1 2.3k+1 2 3.3k+1 1 2 3k+2 2 (a) In your opinion, which of the following statements best describes the claim and purported proof above? Briefly explain your choice. 1. The claim itself is false, and thus the proof must be invalid. 2. The claim is true, but the proof has an error. 3. The claim is true, and the proof is logically valid. But it is not written well (e.g., hard to follow, lack of explanations between steps, etc.). 4. The claim is true, and the proof is correct and well-presented. (Hint: It's not this one.) (b) If you decided in (a) that the given claim and purported proof belongs to Case 1,2, or 3, can you provide a revision of the claim and/or the proof that would belong to Case 4?
