Important Terms Related to Sequences & Series
  • A sequence is a function whose domain is the set N of natural numbers or some subset of it.
  • In an A.P., the sum of the terms equidistant from the beginning and from the end is always same, and equal to the sum of the first and the last term.
  • If three terms of A.P. are to be taken then we choose then as a – d, a, a + d.
  • If four terms of A.P. are to be taken then we choose then as a – 3d, a – d, a + d, a + 3d.
  • If five terms of A.P are to be taken, then we choose then as: a – 2d, a – d, a, a + d, a + 2d.



  • A sequence is said to be a progression if the term of the sequence can be expressed by some formula.
  • A sequence whose range is a subset of R is called a real sequence.
  • In a G.P., the product of the terms equidistant from the beginning and from the end is always same and equal to the product of the first and the last term.
  • If each term of a G.P. be raised to some power then the resulting terms are also in G.P.
  • If a, b, c are in A.P. then 2b = a + c.
  • If a, b, c are in G.P. then b² = ac.
