1.	Consider a sequence {an} with a1=2 and an=a2n−1an−2for all n≥3, terms of the sequence being distinct. Given that a2 and a5 are positive integers and a5≤162 then the possible value(s) of a5 can be
Answer» Consider a sequence ${a_{n}}$ with $a_{1} = 2$ and $a_{n} = \frac{a_{n - 1}^{2}}{a_{n - 2}}$ for all $n \geq 3$ , terms of the sequence being distinct. Given that $a_{2}$ and $a_{5}$ are positive integers and $a_{5} \leq 162$ then the possible value(s) of $a_{5}$ can be
