Answer
This is not an arithmetic sequence.
Work Step by Step
The difference between consecutive terms is constant in an arithmetic sequence.
The sequence: 2, 11, 21, 32, ...
Finding the pattern:
Difference between 1st and 2nd term:
2nd term-1st term=Difference
11-2= 9
Difference between 2nd and 3rd term:
3rd term-2nd term=Difference
21-11= 10
Difference between 3rd and 4th term:
4th term-3rd term=Difference
32-21= 11
The common difference is not constant and thus this is not an arithmetic sequence.
