The number of representatives from a state could increase if the number of representatives from another state increased. the number of districts in the state increased. the number of senators increased. the state population increased.

The number of representatives from a state could increase if the state population increased, because in the constitutional convention in Philadelphia carried out in 1787, it was promulgated the "Great Commitment", where Roger Sherman proposed that the number of representatives in the house of representatives would be determined according to the population amount of each state, and in the Senate there would be an equal representation by each state and not proportional, whereby on July 16, 1787 that Congress Representation Plan was approved and was implemented from that moment until the present. So for that reason, The number of representatives from a state could increase if the state population increased.
