This is not an arithmetic sequence.

Work Step by Step

The difference between consecutive terms is constant in an arithmetic sequence. The sequence: -3, -7, -10, -14, ... Finding the pattern: Difference between 1st and 2nd term: 2nd term-1st term=Difference -7-(-3)= -4 Difference between 2nd and 3rd term: 3rd term-2nd term=Difference -10-(-7)= -3 Difference between 3rd and 4th term: 4th term-3rd term=Difference -14-(-10)= -4 The common difference is not constant and thus this is not an arithmetic sequence.
