6 Answers6 Hint consider the the set of all subsets of { 1, 2, , n } (of which there are 2 n) and try to find the total sum of the sizes of the subsets in two different ways For example, the possible subsets of { 1, 2 } are { }, { 1 }, { 2 }, { 1, 2 } Then adding up the sizes of each subset gives 0 1 1 2N i=2 (1 1 2), where n 2Z and n 2 Proof We will prove by induction that, for all integers n 2, (1) Yn i=2 1 1 i2 = n 1 2n Base case When n = 2, the left side of (1) is 1 1=22 = 3=4, and the right side is (21)=4 = 3=4, so both sides are equal and (1) is true for n = 2 2 Math 213 Worksheet Induction Proofs III, Sample Proofs AJ Hildebrand Induction step Let k 2 be given and suppose My Patreon page https//wwwpatreoncom/PolarPiHere is a full playlist on Induction (More Fun Examples all Examples you need) https//wwwyoutubecom/wat

 f (n)f (n1)=n f (n)−f (n−1) = n, and we will prove f ( n) f ( n − 1) = n 2 f (n)f (n1)=n^2 f (n)f (n−1) = n2 by induction Since the proposition is true for n = 1 n=1 n= 1, let us assume it is true for n = k n=k n = k Now forN 2 " ···!N = (n2 1)/(n−2) diverges to ∞ Proof For n ≥ 3 we have a n ≥ n2/n = n, and we already know that lim n→∞ n = ∞ By comparison theorem {a n} diverges to ∞, too 4 241 Give an example of a sequence that diverges to ∞ but is not eventually increasing a n = n(−1)n 242 Give an example of a converging sequence that does not attain a maximum value a n = −1/n 24
