Question

The eighth term of the geometric sequence -3, 9, -27, 81, .... is

Answer 1

Answer:

The magnitude of the momentum, = 2, is constant. So, the force is not changing the magnitude of the momentum – it is only changing its direction. The component of the force along the momentum is 0. The component perpendicular to it is non-zero, because the momentum is actually changing

Answer 2

Answer:

6561

Step-by-step explanation:

given:-

a(first term)= -3

r = 9/-3= -3

now we will apply nth term formula:-

nth term = ar^n-1

8th term = -3× (-3)^8-1

= -3(-3)^7=6561
