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....

Answer 1

Explanation:

hello:

this sequence is geometric when the common ration is

r = 0.6/-1.2 = -1.2/2.4=2.4/-48 =-4.8/9.6= -0.5

recursive formula is : An =-0.5An-1

Answer 2

f(n + 1) = –0.5f(n)
