Which statements describe the sequence –3, 5, –7, 9, –11, …? check all that apply.
the sequence has 5 terms.
the 4th term of the sequence is 9.
f(5) = 2
the domain of the sequence is all natural numbers.
(4, 9) lies on the graph of the sequence.

What you have provided does have 5 terms, though the sequence could be, and likely is continuing, so could very well have more. Take that how you will.

The 4th term of the sequence is 9.

Can't answer that one without knowing, or seeing, the function of f(x).

The sequence you have provided are all natural numbers, yes.

Again, we need to see the function.
