If you mean: 15 11 7 3 then the nth term is 19-4n
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
It is: nth term = 5-4n and so the next term will be -19
The simplest, out of infinitely many possible answers, is the linear polynomial,U(n) = 4n - 1 for n = 1, 2, 3, ...
The nth term is 7n-3 and so the next term will be 39
The nth term in this sequence is 4n + 3.
If you mean: 15 11 7 3 then the nth term is 19-4n
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
It is: nth term = 5-4n and so the next term will be -19
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
The simplest, out of infinitely many possible answers, is the linear polynomial,U(n) = 4n - 1 for n = 1, 2, 3, ...
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
The nth term is 4n-1 and so the next term will be 19
The nth term of the sequence is 2n + 1.
11
3 11
The nth term is 2 + 3n.
