Question

Which recursive formula can be used to generate the sequence shown, where f(1) = 9.6 and n > 1?

9.6, –4.8, 2.4, –1.2, 0.6, ...

f(n + 1) = –0.5f(n)
f(n + 1) = 0.5f(n)
f(n + 1) = f(0.5n)
f(n + 1) = f(–0.5n)

Answer 1

plug in 1 for n and 9.6 for f(n) and see which one of the options fit

Answer 2

so for example, try th first one:-

f(1 +1) =f(2) = -0.48 should equal -(0.5)* 9.6

Answer 3

thank you

Answer 4

what does -0.5 * 9.6 work out to ?

Answer 5

yw

Answer 6

f(n+1)=-0.5f(n)

Answer 7

f(n+1)=-0.5f(n)

Answer 8

thank you
