Answer:

Recursive formula:

a_n = a_n-1 + 14,

a_1 = 16.5

Explicit formula: a_n = 14(n - 1) + 16.5

Each movie costs the same amount.

Explanation:

Looking at the numbers we see that each next term a_n is 14 added to the previous term, a_n-1 and the first term a_1 is 16.5; therefore, we can say


\begin{gathered} a_n=a_(n-1)+14, \\ a_1=16.5 \end{gathered}
