## Important Sequence and Series Topics in Bank Exams

Sequence and series topics for bank exams are as follows:

 Topic Explanation Sequence A string of numbers generally associated with a common rule is a sequence. Series A summation of numbers generally associated with a common rule is a series Progression 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
