My teacher said I have this backwards,

Question

Here is the question: Formulate the recursive formula for the following geometric sequence.
{-16, 4, -1, ...}

And here is my answer:
A(n+1) = A(n) * -1/4
An+1 = An * r
is
An+1 = An * (-1/4)
Please correct it

Answer 1

nope. you are quite correct!

Maybe she wants it as

An = An-1 * -1/4
or
An+1 = An/4

Answer 2

For the first?
