Answer 1

Notice that we multiply each time by (-3).

Answer 2

my first answer was -1*-3^(n-1) but that didnt work

Answer 3

If a1=-1 then the general term would be exactly as you said.

Answer 4

then what did i do wrong?

Answer 5

Who told you it was wrong ?

Answer 6

my hw is online. you put in an answer and it tells you if you are right or wrong

Answer 7

Did you try replacing -1 by a1 like this : \[a _{n}=a _{1}*(-3)^{n-1}\]

Answer 8

a1 isnt going to be recognized. only some variables are. in this case the only one is n

Answer 9

Well it must be just a bug because your answer is correct :)

Answer 10

ok thanks

Answer 11

\((-1)(-3)^{n-1} = - (-3)^n/ (-3) = 1/3 (-3)^n\)
try this

Answer 12

(1/3) (-3)^n
