Asequence is defined recursively using the formula f(n + 1) = –0.5 f(n) . if the first term of the sequence is 120, what is f(5)? i need answer as soon as possible!

ANSWER

EXPLANATION

The recursive definition is

.

Since the first term of the sequence is given to us, we need to plug in .

This implies that;

.

But we were  given that, .

This implies that;

Since we now know that , we again plug in in to the recursive definition.

.

We plug in to the formula again to determine the 4th term.

.

.

We finally find the 5th term by substituting .

huh? im pretty sure it is in 199

step-by-step explanation:

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
