    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

    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.
