Write the first four terms of the sequence whose general term is given.
-$$a _ { n } = 4 ( 3 n - 1 )$$
A) $8,20,32,44$
B) $2,5,8,11$
C) $- 4,8,20,32$
D) $8,16,24,32$

Quizplus · Accepted Answer

The first four terms are found by substituting $n = 1, 2, 3, 4$ into the formula $a_n = 4(3n - 1)$. For $n = 1$, $a_1 = 4(3(1) - 1) = 8$; for $n = 2$, $a_2 = 4(3(2) - 1) = 20$; for $n = 3$, $a_3 = 4(3(3) - 1) = 32$; for $n = 4$, $a_4 = 4(3(4) - 1) = 44$.
