Answer :![a_{n+1}=a_n+8](/tpl/images/0725/7756/7fc82.png)
Step-by-step explanation:
The given explicit formula :
, where n is a natural number.
At n=1 ,![a_1=8-3=5](/tpl/images/0725/7756/facde.png)
At n=2,![a_2=8(2)-3=16-3=13](/tpl/images/0725/7756/da4d1.png)
At n=3 ,![a_3=8(3)-3=24-3=21](/tpl/images/0725/7756/4480a.png)
We can see the common difference is 8.
So we can write![a_{n+1}=a_n+8](/tpl/images/0725/7756/7fc82.png)
Hence, the recursive formula for the explicitly defined sequence is![a_{n+1}=a_n+8](/tpl/images/0725/7756/7fc82.png)
