Question

The terms in a sequence can be found using the recursive rule f(n)=f(n-1)-2. Fill in the missing terms. 3,(blank), -1, (blank)The blank is what needs to be replaced and filled out. Please help!

Answer 1

The recursive formula is given by

`f(n)=f(n-1)-2`

Now let

`f(n-1)=3`

Then

`f(n)=f(n-1)-2\Rightarrow f(n)=3-2\Rightarrow f(n)=1`

And let

`f(n-1)=-1`

Then

`f(n)=f(n-1)-2\Rightarrow f(n)=-1-2\Rightarrow-3`

So the answer is 3,1,-1,-3
