State If This Is Geometric Or Not:, 100,-50,25,25/2

State if this is geometric or not:
100,-50,25,25/2

 

Answer: the sequence is a not geometric sequence

Step-by-step explanation:

A geometric sequence can be determined if it has a constant number being multiplied to the next terms of the sequence or the common ratio.

At can be determined by dividing the preceedinging term to the previous term

-50÷100= -1/2

25÷ (-50)= -1/2

25/2÷25= 1/2

Since the there was no common ratio in the sequence because of the differences in the qoutient, it is not a geometric sequence.
