Number Series

We Are Starting reasoning from Number Series because Number Series is a vary easy and basic Chapter in reasoning . There is only four main and easy Point in this, lets Start its.

Number series is sequence formed of numbers, we can find the number/ answer easily just detect the rules and get your answer following are some types in number series

  • Next number in the series.

  • Odd man out in the series.

  • Wrong number in the series.

  • Miscellaneous Question in Number Series

 

Next number in the series.

In this type we  jus find the next number in the series its very easy lets explain with the following example :-

 Q) 5, 10, 15, 20, ?

Ans :-  Just find different between first and second term

10 -5 = 5

15-10= 5

20-15= 5

 so the different between two term is 5, than final answer is add 5 in last term 20+ 5 =  25 

 

 Q ) 4, 7, 23, 89 , ?

 Ans : – 

  (4 * 2 ) – 1 = 7

  (7* 3 ) + 2 = 23

  (23 * 4 )  – 3 = 89

 So our final Answer is   (89  * 5 ) + 4 = 449

 

 Q)19,  20, 24, 33, 49, 74, …

hints (Square Difference)

Ans : – 

  20 – 19= 1( 1)

  24 – 20 = 4 ( 2)

  33 – 24 = 9 ( 3)

  49 – 33 = 16 ( 4)

  74 – 49 = 25 ( 5)

so every two term different is square of number and is increase by 1 means our final answer is  = last term of series +  6

                                                                                                =74 + 6

                                                                                               = 74 + 36

                                                                                          = 110

So our final Answer is    = 110

Q) 1, 4, 9, ?, 25, 36, 49, 64, 81, 100

Ans : –   

In the question square of the nature number like  1,2,3,4,…..10 but at a place of question mark missing number is 4 means our answer is square  of 4

So our final Answer is    = 42= 16

Q)  5, 6, 9, 14, 21, ?

Ans:

number-series-logical-reasoning-introduction---number-series-problems

Look at the diagram the different between two term is increase by + 2

So our final Answer is    =21 + 9 = 30
