What is

**SERIES**?

**SERIES**is an important part of the Reasoning section in competitive Examinations. Series is a group of elements which follows a fixed pattern.

**Example:**1) 2,4,6,8,10,12 (Number Series)

3) -,=, △, ▭ (Non-verbal Series)

**NUMBER SERIES:**For better understanding , we will classify this in to five types.

**1. Difference Series :**If the given Series is increase (or) decrese with a normal difference then that Series is Difference Series.

**Example:**18,22,26,30,34,38 (constant difference) .

**Example:**9,14,18,21,23,24 .

**2.Product Series :**If the given series is increase (or) decrease with a abnormal difference then that Series might be product Series .

**Example:**3,6,18,7,360,2160 (Here multiplying *2 ,*3,*4,*5,and *6).

**Example:**16,8,8,12,24,60,180 (Here multiplying *0.5,*1,*1.5,*2,*2.5 and *3 ).

**3.Combination Series:**If the given Series has more than one type of operation performed (or) more than one series combined together is a combination Series.

**Example:**6,18,22,110,116,812 (*3,+4,*5,+6 and *7).

**Example:**6,20,43,131,265,789 (*3+2,*2+3,*3+2, and *2+3).

**4.Squares and Cubes Series:**If the given Series is related to the squares of the numbers (or) cubes of numbers (or) near to squares and cubes then that Series is called squares and cubes Series .

**Example:**4,16,5,25,6,36,7,49( Here number and its squares).

**Example:**16,36,64,100 ( Here even numbers squares).

**Example:**16,36,64,81( Here composite numbers squares).

**5.General Series:**

**Example:**2,3,5,7,11,13,17,19 ( A Series of Prime Numbers).
