Question

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.

Answer 1

we have that
[–3, 5, –7, 9, –11]

a1=-3
a2=5
a3=-7
a4=9
a5=-11

total terms of the sequence is 5

the answer is

The sequence has 5 terms.---------> is correct
The 4th term of the sequence is 9.-----> is correct (a4=9)

Answer 2

The 4th term of the sequence is 9.

The domain of the sequence is all natural numbers.

(4, 9) lies on the graph of the sequenced

Explanation:

sequence –3, 5, –7, 9, –11......

First term is -3, second term is 5, third term is -7 , fourth term is 9 and fifth term is -11

So we are given with 5 terms in the sequence but the sequence continues . It does not stop with 5 terms.

fourth term is 9.The 4th term of the sequence is 9.

Natural numbers are the positive integers . Domain is the input of the sequence. Input is the number of terms. So domain is all natural numbers.

Fourth term of the sequence is 9 . So (4,9) lies on the graph.
