Answer:
The answer is
Step-by-step explanation:
Usng the formula
[tex]A(n) = 3(2) ^{n - 1} [/tex]
Where n is the number of terms
For the first term
[tex]A(1) = 3(2)^{1 - 1} \\ = 3(2) ^{0} \\ = 3(1) \\ \\ = 3[/tex]
For the fourth term
[tex]A(4) = 3(2)^{4 - 1} \\ = 3 ({2})^{3} \\ = 3 \times 8 \\ \\ = 24[/tex]
For the eighth term
[tex]A(8) = 3 ({2})^{8 - 1} \\ = 3 ({2})^{7} \\ = 3(128) \\ \\ = 384[/tex]
