Questions and Answers

What is the basic idea behind mathematical induction?

  • To generalize mathematical statements for all real numbers.
  • To prove that a formula is true for all positive integers by showing it is true for n = 1 and n = 2. (correct)
  • To illustrate the Domino Effect with mathematical formulas.
  • To verify certain mathematical statements using inductive reasoning.

What is the initialization step in mathematical induction?

  • Proving the statement for n = 1 and n = 2. (correct)
  • Illustrating the Domino Effect with simple cases.
  • Using the assumption in Step 2 to prove the statement for n = k + 1.
  • Generalizing the statement for all positive integers.

How is the induction or generalization step different from the initialization step in mathematical induction?

  • It focuses on proving the statement for n = 1 and n = 2.
  • It uses inductive reasoning to illustrate the Domino Effect.
  • It involves proving the statement for n = k + 1 using the assumption from Step 2. (correct)
  • It verifies the formula for all positive integers.
