Question

Consider the following recurrence relation and initial conditions. $t_k = 14t_{k-1} - 49t_{k-2}$, for each integer $k \ge 2$ $t_0 = 1$, $t_1 = 7$ (a) Suppose a sequence of the form $1, t, t^2, t^3, \dots, t^n, \dots$, where $t \ne 0$, satisfies the given recurrence relation (but not necessarily the initial conditions). What is the characteristic equation of the recurrence relation? What value of t is a solution to this equation? $t = $ (b) Suppose a sequence $t_0, t_1, t_2, \dots$ satisfies the given initial conditions as well as the recurrence relation. Fill in the blanks below to derive an explicit formula for $t_0, t_1, t_2, \dots$ in terms of $n$. It follows from part (a) and the single roots theorem that for some constants $C$ and $D$, the terms of $t_0, t_1, t_2, \dots$ satisfy the equation $t_n = $ for every integer $n \ge 0$. Solve for $C$ and $D$ by setting up a system of two equations in two unknowns using the facts that $t_0 = 1$ and $t_1 = 7$. The result is that $t_n = $ for every integer $n \ge 0$.

Step 1

Step 1: To find the characteristic equation of the recurrence relation, we substitute t_k = t^n into the recurrence relation: t^n = 14t^(n-1) - 49t^(n-2) Show more…

Consider the following recurrence relation and initial conditions. t_(k)=14t_(k-1)-49t_(k-2), for each integer k>=2 t_(0)=1,t_(1)=7 (a) Suppose a sequence of the form 1,t,t^(2),t^(3),dots,t^(n)dots, where t!=0, satisfies the given recurrence relation (but not necessarily the initial conditions). What is the characteristic equation of the recurrence relation? What value of t is a solution to this equation? t= (b) Suppose a sequence t_(0),t_(1),t_(2),dots satisfies the given initial conditions as well as the recurrence relation. Fill in the blanks below to derive an explicit formula for t_(0),t_(1),t_(2),dots in terms of n. It follows from part (a) and the single hat(v) roots theorem that for some constants C and D, the terms of t_(0),t_(1),t_(2),dots satisfy the equation t_(n)=|, for every integer n>=0. Solve for C and D by setting up a system of two equations in two unknowns using the facts that t_(0)=1 and t_(1)=7.
