Answer:
f(n+1)=f(n)-99.4
Step-by-step explanation:
We are given a sequence as:
99.4,0,-99.4,-198.8, and so on
We can see that the sequence is constantly getting decreased by -99.4
i.e. f(1)=99.4
Then, f(2)=f(1)-99.4
=99.4-99.4
=0
f(3)=f(2)-99.4
=0-99.4
=-99.4
Hence, the recursive formula is:
f(n+1)=f(n)-99.4
