Binomial theorem

Hello!

I have questions on the binomial theorem. I thought they looked alright and attempted them, only to find that I could not solve them, or my answers are wrong...

1.) Find the value of n if the coefficient of x^3 in the expansion of (2+3x)^n is twice the coefficient of x^2.
2.) In the binomial expansion of (1+(1/3))^n in ascending powers of 1/3, the fourth and fifth terms are equal. Find the value of n.
