Answer 1

`\text{b. }786,432`

Explanation:

The
`n`th term of a geometric sequence is given by
`a_n=a_1\cdot r^(n-1)`.

What we know:

• 
  `a_1` is 3
• 
  `r` is 2 (common ratio, each term is being multiplied by 2)

Substituting given values, we get:

`a_(19)=3\cdot 2^(19-1),\\a_(19)=3\cdot 2^(18)=\boxed{\text{b. }786,432}}`

Answer 2

answer is option B since they are in GM
