Question

Please please help!! The first four terms of a sequence are shown below:

6, 2, -2, -6

Which of the following functions best defines this sequence?

f(1) = 6, f(n + 1) = f(n) + 4; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) - 2; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) - 4; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) + 2; for n ≥ 1

Answer 1

Ignore the answer choices

what's the rule for "6, 2, -2, -6"

Answer 2

-4?

Answer 3

be more specific

Answer 4

How so?

Answer 5

what do you mean by "-4"

Answer 6

Oh well if you subtract four from six you get two. Four from two you get negative two and so on

Answer 7

good, or if you add -4 to each term, you get the next term

Answer 8

f(n+1) is the next term after f(n)

which is why the rule is f(n+1) = f(n) + (-4) or f(n+1) = f(n) - 4

Answer 9

Thank you!
