Important Sequence and Series Topics in Bank Exams

Sequence and series topics for bank exams are as follows:




A string of numbers generally associated with a common rule is a sequence.


A summation of numbers generally associated with a common rule is a series


Special types of sequences are known as progressions.

Arithmetic Progression (AP)

A sequence in which consecutive numbers are associated by a common additive is an arithmetic progression.

Arithmetic Mean (AM)

The summation of values divided by the number of values is the arithmetic mean of the values.

Geometric Progression (GP)

A sequence in which consecutive numbers are associated with a common multiplicative is a geometric progression.

Geometric Mean (GM)

The nth root of the product of n numbers is the geometric mean of the numbers.

Arithmetic - Geometric Progressions (AG)

When every term of an arithmetic progression is multiplied by the corresponding terms of a geometric progression is known as an arithmetic-geometric progression.

Harmonic Progression (HP)

A sequence in which reciprocals of consecutive numbers are associated by a common additive is a harmonic progression.

Harmonic Mean (HM)

The number of values divided by the summation of the reciprocals of the values is known as the harmonic mean of the values. 

Tips to Prepare Sequence and Series Questions for Banking Exams

  • Always attempts the easy questions first.
  • Try to look for patterns such as AP, GP, and HP in the series or sequence given.
  • Remember the properties of AP, GP, and HP when solving series since the sum rule comes into play a lot.
  • The relation between AM, GM, and HM must be at your fingertips.
  • When AP, GP, and HP are not present, try looking for an AGP.

Importance of Sequence and Series in Quantitative Section of Competitive Banking & Government Exams
