WebHence, we can assume the closed form solution to a n is some type of exponential function in n. Simply, let a n = r n for some constant r to be determined. For the recurrence relation you provided, we can make a substitution: r n = r n − 1 + 2 r n − 2 Dividing both sides of the equation by r n − 2, knowing that r n − 2 is not zero for n > 2, yields WebFinding a recurrence relation for a sequence given its closed-form Definition A solution to a recurrence relation gives the value of x_n xn in terms of n n, and does not require the value of any previous terms. Solve the recurrence relation: x_1=3,\ x_n=3x_ {n-1} x1 = 3, xn = 3xn−1 Each term in the sequence can be calculated with a previous term.
