A progression is a number of things in a series, whereas a series is a set or sequence. One of the most common examples of Progression and Series is arithmetic progression.
Sequence and Series CAT Questions: Types of Progression
The candidates may find the following three types of progression to solve the CAT Question Paper for this chapter.
- Arithmetic Progression: Arithmetic Sequences are any series in which the difference between each consecutive term is constant.
- Harmonic Progression: If the reciprocals of all the terms in a sequence form an arithmetic sequence, it is said to be in a harmonic sequence.
- Geometric Progression: Geometric Progression is a sequence in which each succeeding term has a fixed ratio between them.
Sequence and Series Questions for CAT: Types of Series
There are the following series types, and the candidates may find these while solving Sequence and Series CAT Questions.
- Arithmetic series: It is the total values of a sequence
- Arithmetic mean: The arithmetic mean is the result of adding two numbers together
- Geometric series: It is the total of all the elements in geometric sequences, i.e., if the ratio between each term and the term before it, is always constant, the series is said to be geometric.
- Geometric mean: The average of two numbers is known as the geometric mean.
- Harmonic mean: The reciprocal of the arithmetic mean is the harmonic mean.
