Question

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

Answer 1

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

Answer 2

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.

Answer 3

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

Answer 4

What is \(a_{n + 1}\)?

Answer 5

the formula for writing a recursive formula

Answer 6

\(\Large \color{midnightblue}{\rightarrow a_{n} = a_{1} + (n - 1)d }\)

d is the common difference.

Answer 7

-4n is the difference in the case.
