Solution:

The numbers are given below as


\lbrace3600,1440,576,230.4,...\rbrace

To figure out the common ratio, we will use the formula below


r=(t_2)/(t_1)=(t_3)/(t_2)=(t_4)/(t_3)

By substituting the values, we will have


\begin{gathered} r=(1440)/(3600)=(576)/(1440)=(230.4)/(576) \\ r=(2)/(5) \end{gathered}

Hence,

The final answer is

The type of sequence is GEOMETRIC

The common ratio is 2/5
