A) $- 6,7 , - 8,9$
B) $- 6 , - 7 , - 8 , - 9$
C) $- 6 , - 14 , - 24 , - 36$
D) $6,7,8,9$

Quizplus · Accepted Answer

To find the first four terms of the sequence, substitute $n = 1, 2, 3, 4$ into the general term formula $a_n = (-1)^n(n + 5)$:- For $n = 1$, $a_1 = (-1)^1(1 + 5) = -6$- For $n = 2$, $a_2 = (-1)^2(2 + 5) = 7$- For $n = 3$, $a_3 = (-1)^3(3 + 5) = -8$- For $n = 4$, $a_4 = (-1)^4(4 + 5) = 9$
