Key Topics to Revise

1

Basic Ideas and Definitions

  • A sequence arranged according to a certain rule is called a sequence.
  • The sequence that follows certain rule is called a progression.
  • An arithmetic progression has a constant difference between consecutive terms.
2

Arithmetic Progression and Its Formulas

  • The first term of an A.P. is represented by a.
  • The common difference of an A.P. is represented by d.
  • The nth term of an A.P. is represented by Tn.
3

Selecting Numbers in Arithmetic Progression

  • If three numbers are in A.P. and their sum is given, they are taken as a-d, a, a+d.
  • If four numbers are in A.P. and their sum is given, they are taken as a-3d, a-d, a+d, a+3d.
  • If five numbers are in A.P. and their sum is given, they are taken as a-2d, a-d, a, a+d, a+2d.
4

Geometric Progression and Its Formulas

  • A geometric progression consists of non-zero numbers.
  • In a G.P., the ratio of any term and its preceding term is constant.
  • The first term of a G.P. is represented by a.
