Well we don't have the choices, maybe they're coming.

We want r(1)=2, r(2)=5, r(3)=8, ...

We can write that

[tex]r(n)=2 + 3(n-1)[/tex]

That's equivalent to

[tex]r(n)=3n-1[/tex]

Hopefully those are the two expressions among the choices.  There are many equivalent expressions but these are the most likely.

Answer:

r (1) = 2; r (n - 1) + 3, for n >_2

and

r (n) = 3n -1

Step-by-step explanation:

yall aint even give us the functions  smh but its only two because r(1) is obv 2 and thats not expressed by any other answers. if u just plug it into the other functions (the ones without the first term) only one of the three work
