PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

What is the recursive rule for the sequence?

−22.7, −18.4, −14.1, −9.8, −5.5, ...

Answer 1

Answer:
`\bold{(B)\ a_n=a_(n-1)+4.3\ \text{where}\ a_1=-22.7}`

Explanation:

`\text{Given the sequence -22.7, -18.4, -14.1, -9.8, -5.5, the difference (d) is +4.3}\\\text{The general form of the recursive rule for an arithmetic sequence is:}\\a_n=a_(n-1)+d\\\text{With the information provided, the recursive rule is:}\ a_n=a_(n-1)+4.3.\\\text{The first term of the sequence}\ (a_1)\ \text{is 22.7}`
