The nth term is 2n+5 and so the next number is 17
2n
2n +3
6n-5 is the nth term of this sequence
3n - 7
It is Un = 3n - 7.
Un = 4n - 13.
The nth term is: 3n+2 and so the next number will be 20

It is not possible to answer the question since a non linear sequence could be geometric, exponential, trigonometric etc.
If the sequence is non-linear, you need to establish how it is defined.
It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b
You need the rule that generates the sequence.
Increase each term by 1.05 and so the next term is 6+1.05 = 7.05
Un = n + 32
