Which best describes the relationship between the successive terms in the sequence shown? 9,-1,-11,-21

Each element is obtained by adding -10 to the previous term

Step-by-step explanation:

Sequence refers to a set of elements such that the elements are arranged according to some rule .

The number of elements in a sequence is called length of sequence .

A sequence can be finite or infinite .

Sequence is said to be finite if it has finite number of elements and said to be infinite if it has infinite number of elements .

Given sequence : 9,-1,-11,-21

We need to describe the relationship between the successive terms in the sequence .

Here, we can see the following relation between elements :

So, each element is obtained by adding -10 to the previous term .

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

5+2x=a
