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.
You need the rule that generates the sequence.
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
Increase each term by 1.05 and so the next term is 6+1.05 = 7.05
Un = n + 32
