Step 1: Make sure that the given set of numbers arranged in some particular order    

because the question says that the set of numbers are in sequence.


Step 2: Explore the given rule

            EXAMPLE: x_{n+1} = ax_n - 3

            Succeeding term = a (preceding term) - 3


Step 3: According to the given rule substitute the values. And simplify

            EXAMPLE: For an attempt to find the x_2

                                x_{n+1} = ax_n - 3

                                      x_2 =  ax_1 - 3

            Substitute the values x_1 [ take x_1 = 1 since n >1), Some times it mention  

            in the question] 

                                x_ 2 = a(1) - 3

                                  x_2 = a – 3
