A. 196,608

B. 786,432

C. - 196,608

D. - 786,432

Answer

A. 196,608

Step-by-step explanation:

-12/3 = - 4

48 / - 12 = - 4 and - 192 / 48 = - 4

This is a geometric sequence with common ratio - 4.

an = a1 r^ (n - 1) so:-

9th term (a9) = 3 * (-4) ^ (9-1)

= 196,608

A. 196,608

It's not hard.
