Answer 1

Answer:  $\bold{(A)\ a_n=500,000(1.1)^{n-1}}$

Step-by-step explanation:

From the data provided, we know the sequence is {500,000; 550,000; 605,000; ... }.  $So, a_1 = 500,000\ and\ r = \dfrac{550,000}{500,000}=1.1$

The explicit rule for a geometric sequence is: $a_n=a_1(r)^{n-1}$

So, the explicit rule for the sequence above is: $a_n=500,000(1.1)^{n-1}$
