Question

How do you determine the first 5 terms if `a_1=2` and `r=3`?

Answer 1

`2,6,18,54,162`

Explanation:

`"since common ratio "r=3`

`"we are dealing with a geometric sequence"`

`"to obtain a term in the sequence multiply the previous"`
`"term by r"`

`a_1=2`

`a_2=3xx2=6`

`a_3=3xx6=18`

`a_4=3xx18=54`

`a_5=3xx54=162`
