# HOW TO ATTEMPT NUMBER SERIES-HOW TO SERIES

Hi Bankersdaily Aspirants,

How is your preparation going on?Friends IBPS RRB Scale 1 is going to be held in a Span of 3 days.This is the most important time of your Preparation,Practice daily Attend atleast 2 to 3 mock test(Prelims Pattern) daily,Analyse how your performance know which is your strongest Section & Attempt that Section in Prelims Exam which is going to be held from 9th September.The Accuracy & Speed increases when you attempt the test regularly.So Attempt Quiz regularly we are posting quiz on each section (Attempt it to increase in your Accuracy)

Today we are going to discuss on the most important topic Number Series,which will be asked for 5 marks in Prelims & as well as in Mains examination.In that 5 question,3 Question will be quite easy and can be solved in 3 minutes.Remaining 2 Question will be quite tougher & we need to think a lot to get the Pattern.If you have time then you can try,if not then attend 3 question which is easy.In this Article we are going to see some of the frequently asked patterns in number series,but we cannot expect the same pattern in the exam.And there is no specific frame work in number series.

FREQUENTLY ASKED PATTERN IN NUMBER SERIES:

2)BASED ON MULTIPLICATION/DIVISION

## #.1 TYPE 1:

Friends,Number Series is found easily by this techniques,In all the types we will be finding the difference of the given numbers and after that we will find the pattern of the series.

1)2000    2515      3030           3545         ?                 4575

When ever a number is given in the number series,Just find the difference between the number.

Here the difference between the numbers is,

2515-2000=515

3030-2515=515

3545-3030=515

From the above difference we can come to conclusion that the common difference of the two numbers=515

Let’s check in the place of ?:

3545+515=4060

4575-4060 should be 515

Therefore,the missing number is 4060.

So,Friends find the difference,so that you may get a chance to identify the pattern.

2)3865      4375      4153        4763          4441        5151            ?

### Friends will you solve by yourself,

Confused with irregular Pattern ,KNOW THE PATTERN
EXPLANATION

I think you tried this Series by finding the difference between the nearest numbers,you will get the difference as 510,222,600 … in a irregular manner.After that you will get panic by just seeing the time in the desktop.Friends don’t panic if you get the numbers in a irregular manner  just find the difference between the alternate numbers

3865      4375      4153        4763          4441        5151             ?

4153-3865=288

4763-4375=388

4441-4153=288

5151-4763=388

The next number would be 4441+288=4729

So friends don’t get confused by just finding the difference between the nearest numbers,If it doesn’t work by finding the difference between the nearest number just continue by finding the difference between the alternate numbers.

## #.2 TYPE 2:

### BASED ON MULTIPLICATION/DIVISION:

1)If the Pattern continues in the format of Whole number then we can conclude the number is multiplied & divided by the whole number.

If the first number is repeated in the place of second number then we can say that,the number is multiplied/divided by 1

If the number in the second place is half the number in the first place then the number is multiplied by .5 or divided by 2

2)If the Pattern is in the format of decimal value then we can say the number is multiplied & divided by a decimal value.

1)4445         2222.5         3333.75               ?          29170.3125

The number series is of decimal value so we can say the number is multiplied/divided by decimal value

By seeing the number we can say the second number is half the first number

4445/2=2222.5

Just analyse the third number don’t keep on finding the difference between the numbers,

3333.75 is greater than 2222.5

So we can say the series in the format of Multiplication,

Just split the number in order to know whether it is multiplied by 1 or more than 1

3333.75-2222.5=1111.25

Here the number obtained after subtraction is less than 2222.5,So,we can say it is multiplied by 1 and with some decimal value

To find the decimal value just divide the number by 2,4 so that we can assume the value

2222.5/2=1111.25

When it is divided by 2 i am getting the exact value,So my series goes like *.5,then 1.5 now after finding this multipliy the number with 2.5,3.5,,,,, to know whether our assumption is right.

4445         2222.5         3333.75               ?          29170.3125

4445*.5=2222.5

2222.5*1.5=3333.75

3333.75*2.5=8334.375

8334.375*3.5=29170.3125

So my assumption works so the Pattern is *.5,*1.5,*2.5,*3.5,….

4445         2222.5         3333.75               8334.375          29170.3125

Friends no one can say perfectly that the number series will definitely follow the series.So Practice lot of number series so that you will come across with numerous pattern.

1)SQUARES/CUBES

2) n²+1,n³+1

3)DIFFERENCE OF DIFFERENCE

4)PRIME NUMBERS

JUST TRY THIS SUM FIND THE MISSING NUMBER

1)     14              14                28          ?        336

84

The Series is

14*1=14

14*2=28

28*3=84

84*4=336

2)1246          1259           1277             ?            1328             1351

1300

The Series is,

1246+13=1259

1259+13+5=1277

1277+18+5=1300

1300+23+5=1328

1328+33=1351

This Series is know as difference of difference

3)9000          9004             ?                  54067          216293

18017

The Series is,

9000*1+2²=9004

9004*2+3²=18017

18017*3+4²=54067

54067*4+5²=216293

4)43            171                  682             2725                   ?                 43579

10896

The Series is,

43*4-1=171

171*4-2=682

682*4-3=2725

2725*4-4=10896

10896*4-5=43579

5)96          192              768                6144               ?                 3145728

98304

The Series is,

96*2¹=192

192*2²=768

768*2³=6144

6144*16=98304

98304*32=3145728
