Find the commom ratio for the following sequence 1/2, -1/4, 1/8, -1/16

Common ratio = -1\2

Step-by-step explanation:

Common ratio is referred to as the ratio by which the sequence is attaining its next value.

In a sequence say,   a_1,a_2,a_3...a_n the common ratio is calculated by :

In The sequence given here : a_1 =1, a_2= -1\4 , a_3 = 1\8 , a_4= -1\16

Common ratio (r) =
