Explanation Given information: The general term of the sequence a n = 2 + ( − 1 ) n n . Formula used: For the terms of the sequence whose general term is given substitute the value for n to obtain the terms. Calculation: Consider, the general term of the sequence a n = 2 + ( − 1 ) n n . For the first term of the sequence substitute n = 1 in a n = 2 + ( − 1 ) n n , a 1 = 2 + ( − 1 ) 1 1 = 2 − 1 = 1.0000 For the second term of the sequence substitute n = 2 in a n = 2 + ( − 1 ) n n , a 2 = 2 + ( − 1 ) 2 2 = 2 + 1 2 = 5 2 = 2.5000 For the third term of the sequence substitute n = 3 in a n = 2 + ( − 1 ) n n , a 3 = 2 + ( − 1 ) 3 3 = 2 − 1 3 = 5 3 = 1.6667 For the fourth term of the sequence substitute n = 4 in a n = 2 + ( − 1 ) n n , a 4 = 2 + ( − 1 ) 4 4 = 2 + 1 4 = 9 4 = 2.2500 For the fifth term of the sequence substitute n = 5 in a n = 2 + ( − 1 ) n n , a 5 = 2 + ( − 1 ) 5 5 = 2 − 1 5 = 9 5 = 1.8000 For the sixth term of the sequence substitute n = 6 in a n = 2 + ( − 1 ) n n , a 6 = 2 + ( − 1 ) 6 6 = 2 + 1 6 = 13 6 = 2.1667 For the seventh term of the sequence substitute n = 7 in a n = 2 + ( − 1 ) n n , a 7 = 2 + ( − 1 ) 7 7 = 2 − 1 7 = 13 7 = 1
