Hi! I'd like to know how to write the next term in the sentence & write a rule for the nth term.

1) 2/3, 3/6, 4/9, 5/12... I know the next term is 6/15 but I don't know how to write the rule for the nth term...

2) 1/3, 1, 5/3, 7/3,...

I don't get this one at all ):

Please and thank you in advance :)

An =(n+1)/3n ?

A(n+1) = An + 2/3

or

An = 1/3 +(2/3)(n-1)
