Answer

$4,12,36,108,324$

Work Step by Step

The general formula to find the nth term of a Geometric sequence is given as: $ a_{n+1}=a_nr $ We are given that $ a_1=4$ so, $ a_2=a_1r = (4)(3)=12 ;\\ a_3=a_2r = (12)(3)=36; \\ a_4=a_3r = (36)(3)=108 ; \\ a_5=a_4r = (108)(3)=324$ Hence, the first five terms are: $4,12,36,108,324$
