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 :)

my bad ^^; its not sentence, its sequence...

An =(n+1)/3n ?
A(n+1) = An + 2/3
or
An = 1/3 +(2/3)(n1)
