#### UGC NET Mathematical Reasoning and Aptitude Paper 1 | Number series | Letter series | Codes and Relationships.

Mathematical reasoning :- Mathematical reasoning is a branch of the Math’s where we can evaluate the reliability of the assertions which are delivered.

Mathematical aptitude:- Testing your ability to use numbers and calculations to answer mathematical issues is known as mathematical aptitude.

Two Types of reasoning

There are two types of reasoning :- (A) Verbal Reasoning (B) Non – Verbal Reasoning

A) Verbal Reasoning :- A verbal reasoning test may include questions that evaluate your ability to identify letter sequences, interpret codes based on letters and numbers, follow written instructions, interpret texts, find words inside words, and find the missing letter to complete words.

Topic we cover under Verbal Reasoning are:-

(a) Number series

(b) Letter series

(c) Codes and Relationships

(B) Non – Verbal Reasoning :- An Non – Verbal Reasoning involves using diagrams and images to solve problems. It measures the capacity to evaluate visual data and resolve issues through verbal reasoning.

(a) Number series :- A series of numbers that follow a pattern is referred to as a number series. Applicants need to identify the incorrect or missing number in the given series.

1 What number comes after 10, 20, 30, and 40 ?

A. In the sequence 10, 20, 30, and 40 follow the pattern of increasing the number 10 every time so final answer is 10, 20, 30, 40 and 50 .

2 What number comes after 17, 34, 51, and 68 ?

A. In the sequence 17, 34, 51, and 68 follow the pattern of multiplying the number 17*1 every time so final answer is 17, 34, 51, 68 and 85 .

17*1 = 17

17*2 = 34

17*3 = 51

17*4 = 68

17*5 = 85

3 What number comes after 7, 14, 28, and 56 ?

A. In the sequence 7, 14, 28, and 56 follow the pattern of Double the number of last one so final answer is 7, 14, 28, 56 and 112 .

4 What is the next number 3,5,7,11,13 ?

A. In the sequence 3, 5, 7, 11, and 13 follow the pattern of increasing the Prime number so final answer is 3, 5, 7, 11, 13 and 17

5 What number comes after 15, 30, 45, and 60 ?

A In the sequence 15, 30, 45, and 60 follow the pattern of multiplying the number 15*1 every time so final answer is 15, 30, 45, 60 and 75.

15*1 = 15

15*2 = 30

15*3 = 45

15*4 = 60

15*5 = 75

6 What is the next number 30, 20, 60, and 40 ?

A. In the sequence 30, 20, 60, and 40 follow the pattern of increasing the alternate number every time so final answer is 30, 20, 60, 40 and 120

7 What number comes after 25, 31, 38, and 46, ?

A. In the sequence 25, 31, 38, and 46 follow the pattern of increasing the number in ascending order so final answer is 25, 31, 38, 46 and 55 .

25+6 = 31

31+7 = 38

38+8 = 46

46+9 = 55
