Answer:
Geometric sequence.
Step-by-step explanation:
Simply defined, a complex sequence is a set of numbers in a sequence, whose numbers include imaginary numbers. In essensce, not all numbers in a complex sequence are real numbers.
A geometric sequence is a sequence in which each number must be multiplied by a number (referred to as the common ratio) to attain the next value in the sequence.
An arithmetic sequence is a sequence of numbers in which one has to add a value to the previous number to attain the next number.
A simple sequence can be defined as a pattern of numbers, such as a list of multiples.
In the given sequecne:
3, 9, 27, 81, 243
One can see that each element is three times the last. Diving any two consecutive elements (elements next to each other) will result in the numerical value of (3). Therefore this is a geometric sequence since it fits all of the criteria of a geometric sequence and even has a common ratio of (3).

I need to see the rest to solve the k but I know that the direct is 50. is there any other part to it so I can solve it
Answer:
a. z-score for the number of sags for this transformer is ≈ 1.57 . The number of sags found in this transformer is within the highest 6% of the number of sags found in the transformers.
b. z-score for the number of swells for this transformer is ≈ -3.36. The number of swells found in the transformer is extremely low and within the lowest 1%
Step-by-step explanation:
z score of sags and swells of a randomly selected transformer can be calculated using the equation
z=
where
- X is the number of sags/swells found
- M is the mean number of sags/swells
- s is the standard deviation
z-score for the number of sags for this transformer is:
z=
≈ 1.57
the number of sags found in the transformer is within the highest 6% of the number of sags found in the transformers.
z-score for the number of swells for this transformer is:
z=
≈ -3.36
the number of swells found in the transformer is extremely low and within the lowest 1%
