Answer:
<h3>dn = -7^n-1</h3>
Step-by-step explanation:
Given the sequence -1,-7,-49,-343,....
We are to find the nth term of the sequence
dn = ar^n-1
a is the first term = -1
r is the common ration = -7/-1 = -49/-7 = 7
n is the number of terms
Substitute
dn = -1(7)^n-1
dn = -7^n-1
hence the nth term of the sequence is dn = -7^n-1
Hello There!
Statistics is a tool used to help people process, summarize, analyze and interpret data for making better decisions.
It helps us with future events if we know what has happened in past.
Helps us make better decisions.
The better we know about the future of an outcome, the more possibility we have to work around it.
