Hello,
a(2)=-6
a(3)=-6*r
a(4)=-6*r²
a(5)=-6*r^3=162
a(5)/a(2)=r^3=162/(-6)=-27==>r=-3
a(1)=-6/(-3)=2
a(2)=2*(-3)
a(3)=2*(-3)²
a(4)=2*(-3)^3
a(5)=2*(-3)^4
a(n)=2*(-3)^(n-1)

Answer:
a). 17 dies can fit in that box
b). 0.5cm of space is remaining
Step-by-step explanation:
Volume of box: length * width * height
V of box = 5 * 4 * 7
= 140cm ³
V of dice = 2 * 2 * 2 (it is a cube)
