Question

I really need help I can’t seem to understand this at all

Answer 1

Given the sequence below

`8,12,18,27`

The sequence above is a geometric series, therefore the formula for the common ratio(r) is

`r=\frac{2ndterm}{First\text{ term}}=\frac{Thirdterm}{2nd\text{ term}}`

Therefore,

`\begin{gathered} r=(12)/(8)=(18)/(12) \\ r=(3)/(2)=(3)/(2) \end{gathered}`

Hence, the answer is

`(3)/(2)\text{ \lparen Option 3\rparen}`
