Answer:
a_n=-\frac{1}{4 a_{n-1}
Step-by-step explanation:
The recursive formula for the geometric sequence is given by:
a_n = a_{n-1} \cdot r
where,
r is the common ratio terms
-16, 4, -1, ...
This is a geometric sequence.
Here, and
Since,
ans so on .....
Substitute the given values we have;
⇒
Therefore, the recursive formula for the following geometric sequence is,
Answer:
A
Step-by-step explanation:
5n+9=2n
5n+9−2n=2n−2n
3n+9=0
3n+9−9=0−9
3n=−9
3n/3=−9/3
n=−3
