FAQs on Types of Number Series Video Lecture - Logical Reasoning (LR) and Data Interpretation (DI) - CAT

1. What are the different types of number series?
Ans. Number series can be classified into various types such as arithmetic series, geometric series, harmonic series, Fibonacci series, and factorial series.
2. What is an arithmetic series?
Ans. An arithmetic series is a sequence of numbers in which the difference between any two consecutive terms is constant. For example, 2, 5, 8, 11, 14 is an arithmetic series with a common difference of 3.
3. What is a geometric series?
Ans. A geometric series is a sequence of numbers in which the ratio between any two consecutive terms is constant. For example, 2, 6, 18, 54, 162 is a geometric series with a common ratio of 3.
4. How does a harmonic series differ from other types of number series?
Ans. A harmonic series is a sequence of numbers in which the reciprocal of each term forms an arithmetic series. For example, 1, 1/2, 1/3, 1/4, 1/5 is a harmonic series. It is different from other types of series as the terms decrease but never reach zero.
5. What is the Fibonacci series?
Ans. The Fibonacci series is a sequence of numbers in which each term is the sum of the two preceding terms. It starts with 0 and 1, and the subsequent terms are obtained by adding the two previous terms. For example, the Fibonacci series starts as 0, 1, 1, 2, 3, 5, 8, 13, and so on.
