The given sequence is an arithmetic progression with a common difference of 2. To find the nth term of an arithmetic progression, we use the formula: (a_n = a_1 + (n-1)d), where (a_n) is the nth term, (a_1) is the first term, (n) is the position of the term, and (d) is the common difference. In this case, the first term (a_1 = 9) and the common difference (d = 2). Therefore, the nth term is (a_n = 9 + (n-1)2 = 2n + 7).
It is: 2n+9
2n + 1
The nth term in this sequence is 4n + 3.
The nth term is 2n+5 and so the next number is 17
2n+5
It is: 2n+9
2n + 1
The nth term is: 2n+7 and so the next number will be 19
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
The nth term is 2n+5 and so the next number is 17
It is: nth term = 5-4n and so the next term will be -19
The nth term is 4n-1 and so the next term will be 19
(2n-1)(-1)n
2n+5
The nth term for that arithmetic progression is 4n-1. Therefore the next term (the fifth) in the sequence would be (4x5)-1 = 19.
