Number series is an important part of the reasoning section. This chapter deals with the series of numbers in which terms follow a certain pattern throughout. The task involved here is to recognize the pattern and complete the given series with the most suitable term.
The following are the different patterns of number series
- Prime Series
- Difference Series
- Product Series
- Binary Series
- Combination Series
- Miscellaneous Series
1. Prime Series :
Ex 1: 7, 11, 13, 17, 19,…..
Here the terms are consecutive primes. Hence, the next term is 23.
Ex 2: 4, 6, 9, 14, 21……
Here the difference between the terms is consecutive primes i.e. 2, 3, 5 and so on.
Therefore, The required term is 21+11=32.
Ex 3: 169, 121, 49, 25,…..
Here, the terms are squares of consecutive primes i.e. (13)2, (11)2, (7)2, (5),….
Therefore, The required term is 3-9.
Ex 4: 8, 27, 125, 343,…..
Here, the terms are cubes of consecutive primes .e. (2)3, (3)3, (5)3, (7)3….
Therefore, The required term is 113-1331.
