Asequence is defined recursively using the formula . if the first term of the sequence is 120, what is f(5)?

F(n+1)=-1/2f(n)

f(n)=-2f(n+1)

given f(1)=120

-2f(1+1)=120

f(2)=-60

f(2)=-2f(2+1)=-60

f(3)=30

f(3)=-2f(3+1)=30

f(4)=-15

f(4)=-2f(4+1)=-15

f(5)=15/2

Hopes it Helps!

f(5)=15/2

Step-by-step explanation:

f(5)=15/2

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz
