Answer: [tex]\bold{(B)\ a_n=a_{n-1}+4.3\ \text{where}\ a_1=-22.7}[/tex]
Step-by-step explanation:
[tex]\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}[/tex]
