13. Sequences, Series, and the Binomial Theorem

List the first four terms of each sequence whose general term is given.

(A) $a_n=5-2n$

List the first four terms of each sequence whose general term is given.

(B) $a_n=n^2-4n+2$

What is the value of the term being asked for?

$a_n=\frac{2n+1}{n+4}$

$a_4=?$
