Answer:
nth term of the geometric sequence
an= -12*3^(n-1)
Step-by-step explanation:
First term
a= -12
Second term
ar= -36
-12r=-36
r=-36/-12
=3
Third term
ar^2= -108
-12(3)^2
= -12(9)
= -108
nth term of the geometric sequence
an=ar^(n-1)
= -12*3^(n-1)
Answer:
the triangle is not right angle triangle
Solution
Here the first term = -2
5th term = -1/8
Now we have to find the common ratio (r)
Fifth term A5 = -1/8
-1/8 =
Here 
Plug in 
in the fifth term and find the value of r.
-1/8 = -2
Taking 4th root, we get
r = 
Now let's find the second term.
first term *r = -2 *1/2 = -1
2nd term = -1
3rd term = second term * 1/2 = -1 * 1/2 = -1/2
4th term = 3rd term *r = -1/2 *1/2 = -1/4
Thank you :)
-2 is the only domain I think. The rest are not. Hope I’ve helped.
