It seems that the term increases 5 at a time, so (if this tendency continues) it's quite clear that the sequence is of the form 5n+k, for some constant "k". With a little experimentation, you can find that "k" should be 2.

t(n) = 12*n + 5
7n - 4
The given sequence is an arithmetic sequence with a common difference of 4 between each term. To find the nth term of an arithmetic sequence, we use the formula: nth term = a + (n-1)d, where a is the first term, d is the common difference, and n is the term number. In this case, the first term (a) is -3, the common difference (d) is 4, and the term number (n) is the position in the sequence. So, the nth term of the given sequence is -3 + (n-1)4 = 4n - 7.
The nth term is: 3n+2 and so the next number will be 20
Just subtract 9.
