Answer 1

Answer:  $\bold{(C)\ a_n=400,000(1.1)^{n-1}}$

Step-by-step explanation:

$\text{The general form for the explicit rule of a geometric sequence is:}\\a_n=a_1(r)^{n-1}\ \ \text{where}\ a_1\ \text{is the first term and r is the common ratio.}\\\\\text{Given the sequence \{400,000; 440,000; 484,000\}}, \\a_1=400,000\ \text{and r}=\dfrac{440,000}{400,000}=1.1\\\text{So,}\ a_n=400,000(1.1)^{n-1}$
