The First Four Terms of a Sequence Are Given $- 5 , - 2 s , - 3 s , - 4 s , K$

Multiple Choice

The first four terms of a sequence are given. Determine whether they can be terms of an arithmetic sequence, a geometric sequence, or neither. If the sequence is arithmetic find the common difference. If the sequence is geometric find the common ratio. $- 5 , - 2 s , - 3 s , - 4 s , K$

A) $\text { arithmetic, } d = - s$
B) $\text { arithmetic, } d = - \frac { 1 } { 2 }$
C) $\text { geometric, } \gamma = \frac { 35 } { 2 }$
D) $\text { geometric, } \gamma = - \frac { 5 } { 4 }$
E) neither
