Im so lost what the answer is

Answer:

Unfortunately, we can't do anything with 41 as it has no factors. Since $3\sqrt{41}$ is already simplified, try submitting that as your answer. If that doesn't work then try un-doing their steps and get rid of the 3:

$3\sqrt{41}$

$\sqrt{41(9)}$

$\sqrt{369}$

Hope this helps!

Answer:

-108

Step-by-step explanation:

About the easiest way to do this for small values of n is to compute each of the terms using the given recurrence relation.

$a_1=4\\\\a_2=-3a_1=-3(4)=-12\\\\a_3=-3a_2=-3(-12)=36\\\\a_4=-3a_3=-3(36)=-108\\\\\boxed{a_4=-108}$

_____

Alternate solution

You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...

$a_n=a_1\cdot r^{n-1} \qquad\text{for first term $a_1$ and common ratio $r$}$
