The common ratio is ${1 \over 3}$, so you will multiply by 1 over 3 to get the next term in the sequence.

$\Large \color{MidnightBlue}{\Rightarrow g_{n} = 1944 * ({1 \over 3})^n }$

anonymous · Answer

what is the 1944 part?

parthkohli · Answer

I've basically simplified this.

It was originally:

$\Large \color{MidnightBlue}{\Rightarrow 648 * ({1 \over 3})^{n - 1} }$
