Solutions to Exercises on Mathematical Induction Math 1210 ...
Thus the left-hand side of (8) is equal to the right-hand side of (8). This proves the inductive step. Therefore, by the principle of mathematical induction, the given statement is true for every positive integer n. 5. 1 + 4 + 7 + + (3n 2) = n(3n 1) 2 Proof: For n = 1, the statement reduces to 1 = 1 2 2 and is obviously true.

Thus, we have two goals for our proofs. •Veracity - we want to verify that a statement is objectively correct. •Exposition - we want to be able to effectively and elegantly explain why it is correct.

Mathematical Induction - Stanford University
web.stanford.eduTheorem: The sum of the first n powers of two is 2n – 1. Proof: By induction.Let P(n) be “the sum of the first n powers of two is 2n – 1.” We will show P(n) is true for all n ∈ ℕ. For our base case, we need to show P(0) is true, meaning the sum of the first zero powers of two is 20 – 1. Since the sum of the first zero powers of two is 0 = 20 – 1, we see
Structural Induction - UMD

www.math.utah.eduNext we turn to proofs by induction. A mathematical sentence P is an (ordinary) sentence that is definitely either true or false. For example: • “There are 5 days in a week” is a false mathematical sentence, • “14 >13” is a true mathematical sentence, and • “5+2 = 8” is another false mathematical sentence, but
