Web2 Answers. s + 1 is a bound for an when n > N. We want a bound that applies to all n ∈ N. To get this bound, we take the supremum of s + 1 and all terms of an when n ≤ N. Since the set we're taking the supremum of is finite, we're guaranteed to have a finite … WebDec 21, 2024 · Figure 4.1.2: (a) The terms in the sequence become arbitrarily large as n → ∞. (b) The terms in the sequence approach 1 as n → ∞. (c) The terms in the sequence alternate between 1 and − 1 as n → ∞. (d) The terms in the sequence alternate between positive and negative values but approach 0 as n → ∞. crypto cyprus tax WebMTH 320 Exam 1 February 15, 2024 5. Let P 1 n=1 a n be a convergent in nite series. 2 For each n; de ne two new sequences by: p n = a n if a n > 0 0 otherwise, q n = a n if a n < 0 0 otherwise.
