Question

What is the type of sequence and the common difference/ratio for question 11

Answer 1

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
