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 WebJul 7, 2024 · Closed formula: an = a + dn. How do we know this? For the recursive definition, we need to specify a0. Then we need to express an in terms of an − 1. If we call the first term a, then a0 = a. For the recurrence relation, by the definition of an arithmetic sequence, the difference between successive terms is some constant, say d.
