Ralph · Answer 1

Well the sequence is each number is multiplied by 4. 5*4=20. 20*4=80. 80*4=320. 320*4=1280. 1280*4=5120. The sixth term is 5120.

Everett · Answer 2

Answer:5120

Step-by-step explanation:

a=5 r=80:20 r=4

Using the formula

Tn=a*r^ (n-1)

Therefore 6th term=5*4^ (6-1)

6th term=5*4^5

6th term=5*4*4*4*4*4

6th term=5120
