Determine the common ratio and find the next three terms of the geometric sequence. i, -1, -

a. i; 1, i, -1

c. -i; -1,- i, 1

b. i; -1, -i, 1

d. -i; 1, i, -1

select the best answer from the choices provided
a
b
c
d

Option A is correct.

Step-by-step explanation:

Common Ratio of  Geometric series is obtained by dividing by each next term of the series to its previous term

here in the problem  two consecutive terms are -1 and -i

  so dividing -i by -1 in order to find common ratio

                r =

Since here common ratio is i  

next 3 terms are given by

Therefore  common ratio is i and next three terms are  1,i and -1

Therefore option A is correct .
