Find a closed form expression that is a solution to the sequence defined by the following recurrence relation and initial conditions (use the method of characteristic equation): az = 30x2 + 40x-2, for all integers k> 2; ao =1, a1 = 2. 1+2x-3x ak-2=c1(4)k-2+c2(-1)k-2 9k=9(4)k+c2(-1)k 5d=3 d=3/5 final: ak=$4k+(-1)
