This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:
8/-2=-32/8=128/-32=r=-4
The first term is -2
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.
Since we know r and a for this problem already we can say:
a(n)=-2(-4)^(n-1)
2,5,1,10 that is what it is right bro
Answer:
3 1/6
Step-by-step explanation:
19/6= 3.1666666666666 also known as 3 1/6
check your work by multiplying 3 1/6 by 6 and get 19
Given:
A committee of 6 members is to be chose from the 100 members of the U.S. senate.
To find:
The number of ways to form a committee.
Solution:
We have,
Total number of members = 100
Number of members needs to selected of committee = 6
Number of ways to select r items from total n items is
Number of ways to select 6 members from total 100 members is
Therefore, the total number of ways to form a committee is 
, i.e., equal to 
.
9700*11%=1067
you owe $1067 in interest in one year, so $1067*3 years=$3207 in interest for three years
you'll have to pay $3207 in interest on top of the $9700 you already owe
