7n - 3
It is: 25-7n
Un = 25 - 7n
The nth term is 7n-3 and so the next term will be 39
If you mean: 15 11 7 3 then the nth term is 19-4n
7n - 3
It is: 25-7n
Un = 25 - 7n
The nth term is 7n-3 and so the next term will be 39
The nth term in this sequence is 4n + 3.
The nth term is 18 -3n and so the next term will be 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
Un = 5n - 2
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
The nth term of the sequence is 2n + 1.
