Answer:
162
Step-by-step explanation:
20736 x 729 x 4/216 x 64 x27
Now go ahead and do the cancellations
20736/216 =96
729/27 =27
64/4 =16
so you end up getting 96 x 27 x1 /26
96/16 =6
so you get 27 x 6 =162
This is a geometric sequence with first term a1 = -4 and common ratio r = 4
so nth term = a1* r^(n-1)
= -4 *4^(n-1)
