3n - 7

It is Un = 3n - 7.

The nth term is: 3n+2 and so the next number will be 20

no

Un = 4n - 13.

It is not possible to answer the question since a non linear sequence could be geometric, exponential, trigonometric etc.

You need the rule that generates the sequence.

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

It is the description of a rule which describes how the terms of a sequence are defined in terms of their position in the sequence.

The nth term is 2n+5 and so the next number is 17

It is a sequence of numbers which is called an arithmetic, or linear, sequence.

"Non-linear sequence" is a generic term for just about ANY sequence, each of which will have a different equation.

You first have to figure out some rule for the sequence. This can be quite tricky.

There are infinitely many possible answers. The simplest, linear, rule is Un = 4n - 17 for n = 1, 2, 3, ...

It appears that a number of -79 is missing in the sequence and so if you meant -58 -65 -72 -79 -86 then the nth term is -7n-51 which makes 6th term in the sequence -93
