Divide by negative 3 each time.


3 / -3 = -1

-1 / -3 = 1/3

1/3 / -3 = -1/9
apologiabiology
geometric, times -1/3 each time
the common ratio is -1/3
first term is 3
the explicit formula is
[tex]a_n=3( \frac{-1}{3})^{n-1} [/tex] or
[tex]a_n=-9( \frac{-1}{3})^{n} [/tex]
with the domain being {1,2,3,4}
