    Q.

    At her job, Pat earns $25,000 for the first year and receives a raise of $1,000 each year. The explicit formula for the  nthn^{th}   term of the sequence is  an=25,000+(n1)1000a_n=25,000+\left(n-1\right)1000 . Which rule best represents the equivalent recursive formula?

    answer choices

     an=24,000+1000na_n=24,000+1000n  

     an=25,000+1000na_n=25,000+1000n  

     a1=25,000 ; an=an1+1000a_1=25,000\ ;\ a_n=a_{n–1}+1000  

     a1=25,000; an=an+1+1000a_1=25,000;\ a_n=a_{n+1}+1000
