Is the following sequence arithmetic? If so, identify the common difference.

8,5, 3, 2, ...

sequence is not arithmetic

Step-by-step explanation:

Given:

8,5, 3, 2,

above is not arithmetic sequence

As there is constant difference in consecutive terms in a an arithmetic sequence given by:

d=an - an-1

where

d is common difference

an=nth term

an-1=nth - 1 term

Given sequence

8,5, 3, 2,

d=5-8 = - 3

d-3-5=-2

as the difference is not common above sequence is not arithmetic!
