A. 512

B. 3,072

C. 768

D. 1,536

Answer 2

Answer:

D

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r is the common ratio

r = 6 ÷ 3 = 12 ÷ 6 = 24 ÷ 12 = 48 ÷ 24 = 2

Using a₁ = 3 and r = 2, then

$a_{10}$ = 3 × $2^{9}$ = 3 × 512 = 1536 → D
