Number series

Questions on number series are prevalent in most of the exams. Almost 1-2 Questions come in the exam from this topic.

• These questions are based on numerical sequences that follow a logical rule/ pattern based on elementary arithmetic concepts.
• A particular series is given from which the pattern must be analyzed. You are then asked to predict the next number in the sequence following the same rule
• There are some numbers are wrongly put into the series of number and you need to identify or correct them

UGC NET Reasoning Notes

• Try to analyze the given pattern in UGC NET Mathematical Reasoning and Aptitude Notes such as prime numbers, perfect squares, cubes, series of known numbers like Mathematics progression (AP/GP), etc.
• Next..if you are unable to find the familiar number:-
  • Calculate difference B/W the given series elements
  • Then observe the pattern indifference to see are they following any regular pattern or known numbers like said above.
  • If the numbers are growing slowly its must be addition or subtraction series
  • If the numbers are growing rapidly it might be a Square series or cube or multiplicative series.
  • If the difference or sum doesn’t have any particular pattern it must be an alternate number series.
• Now, You need to t signifies that the series follows a complex
  pattern. Check for cases like multiplying the number and adding/subtracting a constant number from it to reach the pattern.

How to Identify Common Patterns in Number Series

The common patterns asked in number series topic are-

Arithmetic Series – This could be of two types. in which the next term is obtained by adding/subtracting a constant number to its previous term. “common difference” is the key here

Example: 4, 9, 14, 19 [In the given series pattern is continued by adding 5 to the last number each time]

Furthermore, this could be mixed with Arithmetic Sequences with the differences of consecutive numbers themselves form an arithmetic series.

Example: 1, 3, 6, …..[ in the given series 3 – 1 = 2, 6 – 3 = 3, ..
Now, we get an arithmetic sequence 2, 3,]

Geometric Sequence is multiplying by the same value each time.

Example – 1, 3, 9, 27, … [ The pattern is continued by multiplying by 3 each time…]

Prime numbers-

• Squares/ cubes-
• The pattern in differences-

The pattern in alternate numbers-
