What is the recurrence equation for this function?

i <- n
while ( i > 1){
   j <- i
   while ( j < n){
      k <- 0
      while (k < n){
         k = k +2;
      }
      j <- j * 2;
   }
   i <- i / 2;
}

I guess, T(n) =T(n^2/4) + 2/n. or T(n) = M*T(n^2/4) + 2/n

Am I right to guess?

I think something’s gonna have to come to M, but I’m not sure.
