Data Sufficiency

Just curious if I did this right:

For (1) while insufficient, I solved the equation like this n^1=3^n-2, therefore 1=n-2 or n=3 ***Still Not Sufficient

For (2) t/n = 3^n/n Also, not sufficient

Combining the two, 3^n/n translates into 3^3/3 which does produce the answer: n IS a factor of t

Did I get lucky on this one, or is this also a correct way to do this?

Thanks in advance.
