An object starts from rest and falls freely for 20 meters near the surface of planet P. If the time of fall is 2.0 seconds, what is the magnitude of the acceleration due to gravity on planet P

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
