Identify the 19th term of a geometric sequence where a1 = 14 and a9 = 358.80. Round the common ratio and 19th term to the nearest hundredth.

Aa19 ≈ 9,195.53
Ba19 ≈ 31,035.73
Ca19 ≈ 13,185.66
Da19 ≈ 20,690.

The formula of geometric sequence is expressed in the following manner:
an = a1 r^(n-1) where r is the ratio and n is an integer.
Substituting, to find r
358.80 = 14 r^(8) 
r is equal to 1.5

hence, 
a19 = 14* 1.5^(19-1)
a19  ≈ 20,690.
