A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

$a_n=r^{n-1}$

where

a_n----> $n^{th}$ term of the sequence

r ---> is the common ratio

a ---> the first term of the sequence

$a=50\\r=100\%-10\%=90\%=90/100=0.90$

substitute

$a_n=50(0.90)^{n-1}$

For n=12

substitute

$a_n=50(0.90)^{12-1}=16$
