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.

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

_____

<em>Alternate solution</em>

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 $r$}$

Then the 4th term will be ...

$a_4=4\cdot(-3)^{4-1}=4\cdot(-27)=-108$

Answere and How to do

Angelina_Jolie [31]

Answer:

-25

Step-by-step explanation:

if you are multiplying x by -2/5 you have to divide each side by it to get

x = 10 ÷ -2/5

and if you change it to (10/1)/(-2/5)

=(10/1) • -5/2

and whene you multiply them you get -50/2

which is -25/1 or -25
