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

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

r(n)=2 + 3(n-1)

That's equivalent to

r(n)=3n-1

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