f(4) = f(2+2) = f(2)= f(0+2) = f(0) odd f(x) = - f(x) ans is 0.

yup!
also note that since f(-x) +f(x) =0 and putting x=0, we get f(0) =0.

Period = 4
.: f(x) = f(x+4)
put x=0
f(0) = f(4)
also it is an odd function .: f(0) = 0 = f(4)
Hence the answer

f(x) is an odd periodic function
=>f(0)=f(2)=f(4)......=f(2n)=0
so f(4)=0
