REASONING SERIES

                                                            Series  

   In this chapter consist of question which have numerical and alphabetical letters or may be combination of both is given to form a series, these series have some logic or pattern .You have to understand the logic apply for that.

1.         NUMBER SERIES: In This case number(0,1,2,3,4,5,6,7,8,9) or combination is given to find the series. If series increase/decrease slow then check for no addition/subtraction sequentially. If series is growing too fast/increase then multiplication / division of number is possible..if series is sometimes too growing/decrease and sometimes normal or slow  then   that series is mixed of two.

       Example.  

1.        Series is    1,6,15,?, 45,66,91  .find the question mark term.

                   Here you can see that sequence of series is normal thus addition  or subtraction of number is possible.

  Therefore pattern is +5,+9,+13,+17,+21,+25…..

 Therefore required series is  15+13=28

    Thus 28 is correct.

2.       ALPHABETICAL SERIES : In this type of question series in alphabet(a,b,c,d,e,f,g,h,I,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z) is given or combination is given. Then we have find the pattern of that.

                           Example.  

1.        Series is  A,C,F,J,?,?  .THEN FIND THE  ? PLACE.

        HERE  if you look order of alphabet “C” is 2 from “A” and “F” is 3 from ” C”,  “J” is 4 from “F”,thus next will be 5 of “J” thus  “O”  and  next is 6 from “O” is “U”.

    THUS “OU” is correct options.   

3.ALPHA-NUMERIC SERIES: In this type of question combination of both numeric number and alphabetic are possible .

                 Example.  

1.      G4T, J10R, M20P, P43N, S90L .find term that is not fit in series.

               

We can see that first letter have 3 difference .ie  “G” +3 =>”J”  ,similarly.

 We can see that third letter have -2 difference .ie  “T” -2 =>”R”  ,similarly.

Now we can see that second letter…

                                    4, 10, 20, 43, 90

                              4*2+1,9*2+2,20*2+3,43*2+4

Thus wrong term is 10.

4.PATTERN SERIES :  In this type  series consist continuous term of alphabetic or numeric letter.

                                                   

 

Question 1.     . aab_ aaa_bba_ find term that is not fit in series.

a)bba       b)abb   c)bab      d) bab

                                 In this type of  series compare with option ,if you see then there is parren which is repeating .

a)       . aab_b aaa_ b  bba_a

b)      . aab_ a aaa_ b bba_b

c)      . aab_b  aaa_ a bba_b

d)      . aab_b aaa_ a bba_b

                                            

                     In above question option a) is correct becase the series is    aabb/aaabbb/aa
