If f(1) = 160 and f(n + 1) = –2f(n), what is f(4)?

Answer with Step-by-step explanation:

f(1) = 160 and f(n + 1) = –2f(n)

⇒ f(2)= -2×f(1)

        = -2×160

       = -320

⇒ f(3)= -2×f(2)

    = -2×(-320)

   = 640

⇒ f(4)= -2×f(3)

    = -2×640

   = -1280

Hence, Value of f(4) is:

- 1280

answer: -0.5 would be the most likley outcome
