What is the recursive formula for the geometric sequence with this explicit formula?
IRINA_888 [86]

For the given geometric sequence, we have:

a_1 = 9\\\\a_n = (-1/3)*a_{n-1}

So the correct option is B.

<h3>Which is the recursive formula?</h3>

Here we have the geometric sequence:

a_n = 9*(-\frac{1}{3} )^{(n - 1)}

To get the initial value of the geometric sequence, we just need to replace n by 1, so we get:

a_1 = 9*(-\frac{1}{3} )*(1 - 1) = 9

Now, notice that the common ratio is (-1/3), this means that each term of the sequence is (-1/3) times the previous term.

a_n = (-1/3)*a_{n-1}

Then the correct option is B.
