Question #1290b

Answer 1

`T_6=4374`

Explanation:

You can find the `n^(th)` term in a geometric sequence using
`T_n=axxr^(n-1)`
With
`a=` first term
`r=` common ratio
`n=` term in the sequence

`T_7=6xx3^(7-1)=4374`

Hope this helps :)

Answer 2

`a_7=4374`

Explanation:

`"the nth term of a geometric sequence is"`

`•color(white)(x)a_n=ar^(n-1)`

`"where a is the first term and r the common ratio"`

`"here "a=6" and "r=3`

`rArra_7=6xx(3)^6=4374`
