Consider a growing network following the Barabási-Albert model. You don't know the initial number of links, but you do know that, at time step $t=10000$, a node that joined at step $t_i=1600$ has degree $k_i=10$. What would be the degree of a node that joined this same network at time step $t_j=6400$?

1. 5
   
2. 14
3. 30
