## Number System: Quantitative Aptitude Complete Study Material

: – Hello Everyone, in this post, our team provides the detailed information about how number series questions are coming in reasoning and quantitative Aptitude exam. Also can check and get the number series test, shortcut tricks & techniques. Number Series can be of many types of Numbers like Natural numbers, Whole numbers, Prime numbers and others.

### Different types of Number series?

**Integer Number**– There are particular formulas tricks to solve number series. Each number series question is solved in a proper manner. Integer Number series is the sequence of real numbers decimals and fractions. Number series example of this is like 1.3.5.9….. etc. in which what should come next is Solved by number series shortcuts tricks performed by the candidate.

**Rational Number**– These are the numbers which can be written as a fraction or quotient where numerator and denominator both consist of integers. An example of this series is 2/3, ¾, 1.75 and 3.25.

**Arithmetic**– It is a mathematical sequence which consisting of a sequence in which the next term originates by adding a constant. It is solved by a particular formula given by the mathematics Xn = x1 + (n – 1)*d. An example of this series is 5, 7, 12, 17, 22, 27, 32, and 37, in which number 5 is added to its next number.

**Geometric**– It is a sequence consisting of a multiplying so as to group in which the following term starts the predecessor with a constant.

3, 6, 12, 24, 48, 96, 192, in which multiples of 2 are there

**Square Numbers** – These are also known as perfect squares in which an integer is the product of that integer with itself. Formula= Xn= n2. An example of this type of number sequence could be the following:

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169,

**Cube Numbers** – Same as square numbers but in these types of series an integer is the product of that integer by multiplying 3 times. Formula= Xn=N3. Example:-1, 8, 27, 64, 125, 216, 343, 512, 729

**Fibonacci Series** – A sequence consisting of a sequence in which the next term originates by addition of the previous two

Formula = F0 = 0, F1 = 1

FN = Fn-1 + Fn-2. An example of this type of number sequence could be the following

0, 1, 1, 2, 3, 5, 8, 13, 21, 34,

**Even numbers**: – A number divisible by 2 is called an even number.

Example:- 0, 2, 4, 6, – – – – – – – – –

**Odd numbers**: – A number not divisible by 2 is called an odd number.

Example:- 1, 3, 5, 7, – – – – – –

**Composite Numbers**: – Numbers greater than 1 which are not prime are called composite numbers.

Example:- 4, 6, 8, 9, 10, – – – -. 6 -> 1,2,3,6.

**Prime Numbers**: – A number greater than 1 having exactly two factors, namely 1 and itself is called

A prime number

Prime numbers Upto 100 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 71, 73, 79, 83, 89, 97

**Co-prime Numbers:-** 2 natural numbers a and b are said to be co-prime if their HCF is 1.

Example:- (21, 44), (4, 9), (2, 3), – – – – –

**Twin prime numbers**: – A pair of prime numbers (as 3 and 5 or 11 and 13) differing by 2 are

Called twin prime number

Example: – The twin pair primes between 1 and 100 are

(3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73)
