Answer:
(a) 
(b) nth term: 
Step-by-step explanation:
Solving (a)
Given
The first 3 terms.
When n = 1
When n = 2
When n = 3
So, the first three terms are:
Solving (b)
Given
Required
The nth term
The sequence is arithmetic.
So, first calculate the common difference (d)
The nth term is then calculated as:
Where
So:
and
