Decide whether the formula an = –4n(n – 1) is explicit or recursive. Then find the first five terms of the sequence.

Question

anonymous · Answer

this 1 is hard ...i'm confused and p.s i did read the chapter

parthkohli · Answer

This is a recursive formula because it depends on finding the previous terms to find the value of $a_{n}$. Although, you can convert it into an explicit formula by simplifying.

anonymous · Answer

ok @ParthKohli  how do you find the next five terms in the sequence??

parthkohli · Answer

What is $a_{n + 1}$?

anonymous · Answer

the formula for writing a recursive formula

parthkohli · Answer

$\Large \color{midnightblue}{\rightarrow a_{n} = a_{1} + (n - 1)d }$

d is the common difference.

parthkohli · Answer

-4n is the difference in the case.
