A. a1=6

an=an-1*(-4)

B. a1=6

an=an-1*4

C. a1=4

an=an-1*(-6)

D. a1=4

an=an-1*6

Answer:

Option A. [tex]a_{1} =6[/tex]  [tex]a_{n}= a_{n-1}(-4)[/tex]

Step-by-step explanation:

The given sequence in the question is 6,-24,96,-384.......n

and we have to give the recursive formula for this arithmetic sequence.

We can re write the sequence to make it more simpler

6,6(-4),(-24)(-4),(96)(-4).......n terms

Now we can say [tex]a_{1} = 6[/tex]

and [tex]a_{n}= a_{n-1}(-4)[/tex]

Therefore the recursive formula of the sequence is [tex]a_{1} = 6[/tex]

[tex]a_{n}= a_{n-1}(-4)[/tex]
