Answer
$a_1=3$,$a_2=6$,$a_3=12$,$a_4=24$,
$a_5=48$
Work Step by Step
Initial term, $a_1=3$ and common ratio $r=2$.
Now, we need first five terms of a geometric sequence such as:
$a_1=3$;$a_2=3(2)=6$;$a_3=6(2)=12$;$a_4=12(2)=24$;
$a_5=24(2)=48$
Hence, five terms are: $a_1=3$,$a_2=6$,$a_3=12$,$a_4=24$,
$a_5=48$
