Answer 1

The answer is arithmetic, I just took the quiz and got it right. :)

Step-by-step explanation

Answer 2

It is an arithmetic sequence.

Explanation:

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

The sequence 1,3,5,7,.. can be written as following.

`a_(n)=(2*n-1)`

The difference between the consecutive terms is 2 for all terms. Therefore it is an arithmetic sequence.
