Step-by-step explanation:

The first term of arithmetic cequence is -15, the second term is -7, the third term is 1 and i.e.

The difference between two consecutive terms of the arithmetic sequence is the difference of the arithmetic sequence. Thus, the difference of the arithmetic sequence is

Hence,

Next four terms are 9, 17, 25, 33.
