30 Μαρ 2016 · Let your statment be A(n). You want to show it holds for all n ∈ N. You use the principle of induction to establish a chain of implications starting at A(1) (you did that one). What is left to show is A(n) ⇒ A(n + 1) This means you consider n fixed and try to proof A(n + 1).
sigma(1, infinity) (5 + 2n)/(1 + n^2)^2Determine whether the series converges or diverges.
Solution. Verified by Toppr. Let P (n): 1 + 3 + 5 + ..... + (2n - 1) = n2 be the given statement. Step 1: Put n = 1. Then, L.H.S = 1. R.H.S = (1)2 = 1. ∴. L.H.S = R.H.S. ⇒ P (n) istrue for n = 1. Step 2: Assume that P (n) istrue for n = k. ∴ 1 + 3 + 5 + ..... + (2k - 1) = k2. Adding 2k + 1 on both sides, we get.

4 Σεπ 2020 · Best answer. Let the given statement P (n) be defined as P (n) : 1 + 3 + 5 +...+ (2n – 1) = n2 , for n ∈ N. Note that P (1) is true, since. P (1) : 1 = 12. Assume that P (k) is true for some k ∈ N, i.e., P (k) : 1 + 3 + 5 + ... + (2k – 1) = k2. Now, to prove that P (k + 1) is true, we have. 1 + 3 + 5 + ... + (2k – 1) + (2k + 1) = k2 + (2k + 1)
a 1 = 2, a n = 5 a n–1, for all natural numbers n ≥ 2. Use the Principle of Mathematical Induction to show that the terms of the sequence satisfy the formula a n = 2.5 n–1 for all natural numbers. State whether the following proof (by mathematical induction) is true or false for the statement.
