Explanation Given information: The sequence a n + 1 = n + 2 a n − 1 and first term, a 1 = 3 . Formula used: For a recursive sequence of the form a n + 1 , whose first term is known the next terms of the sequence are generated by substituting the previous term to the recursive formula. Calculation: Consider the recursive sequence a n + 1 = n + 2 a n − 1 whose first term, a 1 = 3 . For the second term a 2 of the sequence, substitute the previous terms, that is put n = 1 , in the recursive formula a n + 1 = n + 2 a n − 1 , a 1 + 1 = n + 2 a 1 − 1 a 2 = 1 + 2 a 1 − 1 a 2 = 2 a 1 Substitute the value of a 1 which is 2, to generate the second term, a 2 = 2 ( 3 ) a 2 = 6 Therefore, the second term is 6. For the third term a 3 of the sequence, substitute the previous terms, that is put n = 2 , in the recursive formula a n + 1 = n + 2 a n − 1 , a 2 + 1 = n + 2 a 2 − 1 a 3 = 2 + 2 a 2 − 1 a 3 = 1 + 2 a 2 Substitute the value of a 1 which is 2, to generate the second term, a 3 = 1 + 2 ( 6 ) a 3 = 13 Therefore, the second term is 13
