Answer:
A = {32, 36, 34, 33, 35};
Step-by-step explanation:
The general definition of mean of a set A is:
, where n are the elements of the dataset.
In this case:
Answer:
Arithmetic sequence.
Step-by-step explanation:
We have been given 9,5,1 and -3
We need to check what kind of sequence is this.
d is common difference we will check difference of consecutive terms.
We can see the difference between all the terms are same that is -4
So, this is an arithmetic sequence.
Arithmetic sequence is the sequence in which the difference between consecutive terms are same.
