Find a function f(n), that identifies the nth term of the following recursively defined sequence as an = f(n): a.) a1 = 3, an+1 = 3an for n ≥ 1. f(n) = ? b.) a1 = 5, an+1 = [(n + 1)an] / 5 for n ≥ 1. f(n) = ?

Find a function $f(n)$ that identifies the $n$ th term $a_{n}$ of the following recursively defined sequences, as $a_{n}=f(n).$ $$a_{1}=1 \text { and } a_{n+1}=a_{n} / 2^{n} \text { for } n \geq 1a$$
Recursive Sequences $A$ sequence is defined recursively by the given formulas. Find the first five terms of the sequence. $$ a_{n}=a_{n-1}+a_{n-2} \quad \text { and } \quad a_{1}=1, a_{2}=2 $$
