2. Let, a1= 3 and for n ≥ 2, an = 2an-1 + 1, express an in terms of n. for n ≥ 3, an = 2an-1+ bn-1 for n ≥ 2 bn = bn-1 + an-1 express an in terms of n.
For any integer k greater than or equal to 2, define R(k) as the ratio of k 's largest positive prime divisor to its smallest positive prime divisor. For instance, R(14) = ½, R(15) = 3, R(30) = ½, and R(9) = 3 = 1. Note that R(k) = 1 if k is a prime number or any power of a prime. Additionally, R(1) is defined as 1. Prove or disprove these statements: (a) For every natural number x, there is a natural number y such that the ratio R(y) is at least x. (b) There is a natural number y such that for every natural number x, the ratio R(y) is at least x.

Consider chapter 1.1, exercise 32 of “Elementary Number Theory & It’s Applications”: Prove the following stronger version of Derichlet’s approximation. If α is a real number and n is a positive integer, there are integers a and b such that 1 ≤ a ≤ n and: |aα-b| ≤ 1/(n+1) The following hint was left below: (Hint: Consider n+2 numbers 0,…,{ja},…,1 and the n+1 intervals (k-1)/(n+1) ≤ x < k/(n+1) for k=1,…,n+1.) The original Derichlet’s Approximation Theorem and proof is shown in the first image. The current problem, #32, is shown in the second image.
