Given:
The geometric sequence is:
1 -4
2 20
3 -100
To find:
The explicit formula and list any restrictions to the domain.
Solution:
The explicit formula of a geometric sequence is:
...(i)
Where, a is the first term, r is the common ratio and 
.
In the given sequence the first term is -4 and the second term is 20, so the common ratio is:
Putting 
in (i), we get
where
Therefore, the correct option is B.
Multiply straight across (neg times a neg = a positive)
=28/81
Answer:
Dear Laura Ramirez
Answer to your query is provided below
Option B is correct
Step-by-step explanation:
In a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
Also,
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
Here, if you see( 16+24)>38
So, the set of numbers can be measures of a
triangle.
