Question 1117385:  Write a recursive definition for the sequence 11, 8, 5, 2,...
 
a1=11, an=an-1-4 
a1=11, an=an-1-3 
a1=2, an=an-1-3 
a1=2, an=an-1+3
 
Much of that is meant to be in subscript, however, I don't know how to do subscript on here and couldn't get it to copy paste over, here is a photo, I do apologize that the entire problem can't be seen on here.
 
Here is the photo of the four answers with subscript. https://postimg.cc/image/sszribopz/

You can  put this solution on YOUR website! Write a recursive definition for the sequence 11, 8, 5, 2,...- 
---- 
You see that each successive term is 3 less than its previous term 
and you see that the 1st term in 11. 
So a(1) = 11 and a(n) = a(n-1) - 3  
a1=11, an=a(n-1)-4 
a1=11, an=a(n-1)-3 
a1=2, an=a(n-1)-3 
a1=2, an=a(n-1)+3
