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 :-

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
