WebJul 13, 2024 · So the sequence can be defined by a 1 = 3 and an = a n − 1 + ( 2 n − 1), for every n ≥ 2. We were asked for a 6, and we know that a 5 = 27, so a 6 = a 5 + 2 ( 6) − 1 … WebNow what does x n-1 mean? It means "the previous term" as term number n-1 is 1 less than term number n.. And x n-2 means the term before that one.. Let's try that Rule for the 6th term: x 6 = x 6-1 + x 6-2. x 6 = x 5 + x 4. So term 6 equals term 5 plus term 4. We already know term 5 is 21 and term 4 is 13, so:
