The sequence is a arithmetic sequence if difference between two consecutive terms always remain same. In arithmetic sequence next term can be obtaiend by addition or subtraction of a constant value.

In sequence 4,1, -2, -5,... next term is obtained by substraction of number 3. So this sequence is an arithmetic sequence.

Answer: 4, 1, -2, -5, ...
