Answer:

  • a[1] = -6
  • a[n] = 0.2·a[n-1]

Explanation:

For a geometric sequence, the next term is the present term multiplied by the common ratio. Of course, the first term is the given one.

a[1] = -6 . . . . . . first term

a[n] = 0.2·a[n-1] . . . . . . last term multiplied by the common ratio
