3 Concept Maps

Mathematical Induction Proof Process

Mathematical Induction Proof Process

The map in words

  • Start: State P(n) clearly
    • Verify Base Case
      • P(1) is TRUE: Assume P(k) is true Inductive Hypothesis
        • Prove P(k+1) is TRUE using P(k)
          • Successfully proven: Both conditions met
            • Conclusion: P(n) is true for all natural numbers n
              • End: Statement not proven
          • Cannot prove: Proof FAILS Inductive step failed
      • P(1) is FALSE: Proof FAILS Base case not satisfied

Step-by-Step Mathematical Induction Process

Step-by-Step Mathematical Induction Process

The map in words

  • Start: Given Statement P(n)
    • Step 1: Verify Base Case
      • Is P(1) TRUE?
        • No: Statement FAILS Cannot use induction
          • End
        • Yes: Base case established ✓
          • Step 2: Assume P(k) is TRUE
            • Step 3: Prove P(k+1) is TRUE using the assumption
              • Can you prove P(k+1) from P(k)?
                • No: Try different approach or revise statement
                • Yes: Inductive step proven ✓
                  • CONCLUSION
                    • P(n) is TRUE for all n ∈ ℕ
