Write the first four terms of the geometric sequence with the given first term, a1, and common ratio, r.
-$$a _ { 1 } = 9 ; r = 2$$
A) $9,18,36,72 , \ldots$
B) $9,11,13,15 , \ldots$
C) $2,18,162,1458 , \ldots$
D) $18,36,72,144 , \ldots$

Quizplus · Accepted Answer

The first term is 9, and each subsequent term is found by multiplying the previous term by the common ratio, 2. Thus, the sequence is 9 (first term), 9*2=18 (second term), 18*2=36 (third term), and 36*2=72 (fourth term).
