 Apr 18, 2011 Computing Terms in a Sequence by: Staff The question: (1 pt) List the first four terms of each sequence. an=5n-1: , , , , . bn=(-2)n: , , , , . c1=2cn=-2cn-1-1: , , , , . The answer: Computing terms in the sequence a_n = 5n – 1 its first term is (n = 1): a_1 = 5*1 – 1 = 4 its second term is (n = 2): a_2 = 5*2 – 1 = 9 its third term is (n = 3): a_3 = 5*3 – 1 = 14 its fourth term is (n = 4): a_4 = 5*4 – 1 = 19 final answer: a_n = 5n - 1: 4, 9, 14, 19, . . . ------------------------- b_n = (-2)n its first term is (n = 1): b_1 = (-2)*1 = -2 its second term is (n = 2): b_2 = (-2)*2 = -4 its third term is (n = 3): b_3 = (-2)*3 = -6 its fourth term is (n = 4): b_4 = (-2)*4 = -8 final answer: b_n = (-2)n: -2, -4, -6, -8, . . . ------------------------- c_1=2cn=-2cn-1-1 c_1=2cn=-2cn-1-1 2*c_n = -2c_n -1 -1 2*c_n = -2c_n -2 4*c_n = -2 c_n = -1/2 final answer: c_1 = 2*c_n = -2c_n -1 -1: -½, -½ , -½, -½ ,. . .
