a. 1, 2, 3

b. 0, 8, 16

c. 8, 5, 2

d. 11, 8, 5

Answer 1

The answer is 11,8,5

Explanation:

that's the correct answer

Answer 2

11,8,5

Explanation:

an=11-3(n-1)

Let n=1

a1 = 11 - 3(1-1)

= 11 -0

=11

Let n=2

a2 = 11-3(2-1)

= 11 -3(1)

= 8

Let n=3

a3 = 11-3(3-1)

= 11 -3(2)

= 11 -6

=5
