## The Attempt at a Solution

Sequence i got :

## a_1, a_2, a_3, a_4, a_5 ##

## 3, \frac{9}{4}, \frac{7}{4}, \frac{17}{12}, \frac{43}{36} ##

I tried to find the formula of ##a_n##

##a_n = \frac{3}{2} a_{n+1} - \frac{3}{8} ##

Can i get a clue? Is it necessary to know if it is geometric or arithmetic sequence?
