Answer:
An explicit rule for the nth term of the sequence will be:
Thus, option (A) is true.
Step-by-step explanation:
Given the sequence
A geometric sequence has a constant ratio r and is defined by
Computing the ratios of all the adjacent terms
As the ratio 'r' is the same.
so
as
Hence, the nth term of the sequence will be:
substituting the values and
Therefore, an explicit rule for the nth term of the sequence will be:
Thus, option (A) is true.
Answer:
x=3, y=-1
Step-by-step explanation:
Double the first equation, then add the second
6x+2y=16
+ 2x-2y=8
The y's cancel each other out.
8x=24
x=3
Solve for y
6-2y=8
2y=-2
y=-1
Double check:
6(3)+2(-1)=16
18-2=16
Yay!
