Step-by-step explanation:

(a) (i)

a₁ = 17

a₂ = 17 - 3 = 14

a₃ = 14 - 3 = 11

------------------------------------------------

(ii)

a₁ = 3

a₂ = 5(3) + 2 = 15 + 2 = 17

a₃ = 5(17) + 2 = 85 + 2 = 87

-----------------------------------------------

(b)

There is a common difference d between consecutive terms , that is

d = 11 - 6 = 16 - 11 = 21 - 16 = 5

Thus indicates the sequence is arithmetic with n th term given by

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 6 and d = 5 , thus

= 6 + 5(n - 1) = 6 + 5n - 5 = 5n + 1
