Find the magnitude and direction of 1/2r a.1.8 meters, 85 degrees
b. 0.9 meters, 85 degrees
c. 0.9 meters, 170°
d. 0.9 meters, 255 degrees

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
