Answer:
Option (3)
Step-by-step explanation:
Explicit formula of the sequence is,

From this explicit formula, 
First term of the sequence will be,


Second term of the sequence,

 = 13
 = 13
3rd term of the sequence,

    = 31
Sequence formed,
7, 13, 31 ..........
From the given options,
Recursive formula,



 = 13
 = 13



     = 39 - 8
     = 31
Sequence formed from this recursive formula will be,
7, 13, 31........
Therefore, Option (3) will be the answer.
