Let

$a1=5 \\ a2=10\\ a3=30\\ a4=60\\ a5=180$

we know that

$(a2)/(a1) = (10/5)=2 \\ a2= a1*2$

$(a3)/(a2) = (30/10)=3 \\ a3= a2*3$

$(a4)/(a3) = (60/30)=2 \\ a4= a3*2$

$(a5)/(a4) = (180/60)=3 \\ a5= a4*3$

The pattern is times two then times three then times two then times three

so

the sixth term will be

a6=a5*2

a6=180*2=360

therefore

the answer is
