Find an explicit rule for the nth term of the sequence. 3, -12, 48, -192,

Step-by-step explanation:

Given sequence :

Here, First term

Second term

and  Ratio=

Third term

Ratio=

Fourth term

Ratio=

Thus, the given sequence is geometric sequence with the common ratio r = -4.

The explicit rule for for the nth term in geometric sequence is given by

Then the explicit rule for the nth term of the given sequence will be :-

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

c is the answer
