Find the missing element in below letter series

**Description :**In this series odd placed letters are random letters but even placed letters are having relation with previous odd positioned letters . That means H is related to Z , F is related to O so on. Now let us identify the relation using A through Z series of letters positions .Z's position is 26, After adding individual numbers of Z position leads to 8 and 8th positioned letter H . Same way O's position is 15 , if you add every number present in this position leads to 6 . 6th position letter is F . using same logic you will get G as answer .
Letters Position reference :
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

**Description :**The first and third letters of each term are moved three steps forward and the second letter is moved two steps forward to obtain the corresponding letters of the next term.

**Description :**The first and third letters of each term are moved one step backward and the second letter moved one step forward to obtain the corresponding letters of the next term.

**Description :**The first letter of each term is moved one step forward, the second letter is moved four steps backward and the third letter is moved four steps forward to obtain the corresponding letters of the next term.

**Description :**The first letter of the terms are consecutive letters. The third letter of each term is moved three steps backward to obtain the third letter of the successive term. The middle letters of the first, second, third and fourth terms are moved one, two, three, and four steps forward respectively to obtain the middle letter of the successive terms.

**Description :**The first letter of the first, second, third and fourth terms are moved one, two, three and four steps forward respectively to obtain the first letter of the successive terms. The second letters of the first, second. Third and fourth terms are moved three, four, five and six steps backward respectively to obtain the second letters of the successive terms. The last letter of the terms are alternate.

**Description :**This series is having ascending order of positions of individual letters present in the sets . In the given series F's position is 6 as per alphabetical series . CD's total positions value is 3+4=7 , DD's totals positions value is 4+4=8 , I's position is 9 . same way EF's position is 11 and the answer is L since its position is 12 .

**Description :**The number of letters in the terms goes on increasing by 1 at each step. Each term consists of letters in alphabetical order. The last letter of each term and the first letter of the next term are alternate.

**Description :**The number of letters in the terms goes on increasing by one at each step. Also there is a gap of one letter between the last letter of the first term and first letter of the second term and a gap of two letters between the last letter of the second term and first letter of the third term. So the first letter of the required term would be four steps ahead of the last letter of the third term.

M-13, 0-15

M-14, O-15

M-15, O-17

M-11, N-12

**Description :**The letters in the series are alternate and the numbers indicate their position in the alphabets from the beginning.

**Description :**The letter in the first, second, third and fourth terms are respectively moved one, two, three and four steps forward to obtain the letter in the subsequent terms. The sequence followed by the numbers is +3, +5, +7.

**Description :**The first letter of each term is moved two steps forward and the second letter is moved two steps backward to obtain the corresponding letters of the next term. The numbers in each term is squares of natural numbers.

**Description :**The first letter of each term is odd numbers of alphabets, and the second letter in the series is the odd number in increasing order, and the third letter in the series is in decreasing order with skipping one letter backward.

14ba _ _ _a_ aabb

babb & a

baab & a

abbb & a

abaa & b

**Description :**The series is baa/bba/baa/bba.
Thus the pattern baa, bba is repeated.

**Description :**The series is bab/bab/bab/bab.
Thus the pattern aba is repeated.

16_ _ abaaab _ b _ _

ba,b,aa

ab,b,ba

aa,b,ab

ab,a,aa

**Description :**The series is ababaa/ababaa. Thus the pattern ababaa is repeated.

**Description :**Between first and second letters 2 letters are skipped between 2nd and third 4 letters are skipped between 3rd and 4th letters 6 characters are skipped . hence between 4th and 5th letters 8 letters must be skipped which results in Y as result .

LJA

All options are correct .

**Answer :**

**(D) **All options are correct .

**Description :**In the series when you deduct positions of all letters in any set with the corresponding first letters position you will get 1 as result.
In case of above series z's position is 26 and y's position is 25 , 26-25 results 1 . same way R's position is 18 , M's position is 13 and D's position is 4 , which leads to 18-13-4=1 . Hence all answers are correct .

19A,B,L,V,JD,BM,

CD

G

Y

All options are correct .

**Answer :**

**(D) **All options are correct .

**Description :**The given series is following ascending order of sum of position of set's of elements . A's position in A through Z series is 1. B's position is 2. L's position is 12 and the total value of all number in the letter is 1+2=3 . same way V 's total is 4 so on . using the same logic CD , G and Y's total is 7. hence all the options are correct .

**Description :**The series is following 1^2,2^2,3^2,4^2,5^2,etc.. hence TTX is correct .
