Input advice: . Use * for multiplication, / for division, and ^ for powers. . Entering (for example) B3^n will convert to By. If you want B X 3" then you should enter B*3^n . Check that your answer displays as expected on the preview a ) Find a particular solution to the linear recurrence relation S, - 3S,-1 = 1 - 4n, noting that H, = A * 3" is the general solution to the corresponding homogeneous equation. Trial/particular solution: Pn = Use variables B and C for the unknown constants. LHS = Express your answer in terms of B, C and n. RHS = Express your answer in terms ofn. B = Enter an integer or a fraction. C = Enter an integer or a fraction. The particular solution is Pr = Express your answer in terms ofn. Submit part 5 marks Unanswered b) A particular solution to the recurrence relation S, - 2S,-1 = 2n - 1 is Pn = -2n - 3. The general solution to the corresponding homogeneous equation is H, = A * 2" . Use this information to find the solution of the initial value problem Sn - 2Sn = 2n - 1 for n > 2 with S1 = -1. A = Enter an integer or a fraction. The solution is Sn = Express your answer in terms ofn
