Find the first six terms of the sequence.

a1 = -8, an = 5 • an-1

Answer 1

-8,-40,-200,-1000,-5000,-25000

Explanation:

a1 = -8

Let n = 2

a2 = 5 a1 = 5*(-8) = -40

Let n =3

a3 = 5 * a2 = 5 * -40 = -200

Let n =4

a4 = 5 * a3 = 5 * -200 = -1000

Let n =5

a5 = 5 * a4 = 5 * -1000 = -5000

Let n =6

a6 = 5 * a5 = 5 * -5000 = -25000
