Sequence


Definition:

  • (n.) The state of being sequent; succession; order of following; arrangement.
  • (n.) That which follows or succeeds as an effect; sequel; consequence; result.
  • (n.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences.
