Progression: AP and GP

Given an arithmetic progression is 24, 20,16, find the (a) 10th term and (b) the sum of the first 30 terms.

A geometric progression has a common ratio of 1/3 and the sum to infinity is 30. Find the first term of the progression.

Given that the nth term of the geometric progression  $-\frac{1}{3},\ 1,\ -3,\ 9,\ ...$  is 729, find the value of n.
