In order to fin which type of sequence it is we evaluate the first two terms:
-2 and 0
We know that
-2 + 2 = 0
The following numbers can be found adding a 2:
-2 + 2 = 0
0 + 2 = 2
2 + 2 = 4
4 + 2 = 6
We know that
A sequence in which every term is created by adding a fixed number (2 in this case) is an arithmetic sequence
