Question

In the following question, various terms of a letter series are given with one term missing as shown by (?). Choose the missing term out of the given alternatives.

DF, GJ, KM, NQ, RT, ?

• A. UW
• B. YZ
• C. XZ
• D. UX

Answer 1

D) UX

Answer 2

If we observe series the first term of series follows the patterns like $+3,+4,+3,+4....$ 

• $D+3=G$
• $G+4=K$
• $K+3=N$
• $N+4=R$
• $R+3=U$

while the second terms follow likes $+4,+3,+4,+3...$

• $F+4=J$
• $J+3=M$
• $M+4=Q$
• $Q+3=T$
• $T+4=X$

So correct term is UX.

Option $(D)$ is correct.

Answer 3

$DF, GJ, KM, NQ, RT,$______

• $D\overset{+2}{\rightarrow} F \overset{+1}{\rightarrow} G$
• $G\overset{+3}{\rightarrow} J \overset{+1}{\rightarrow} K$
• $K\overset{+2}{\rightarrow} M \overset{+1}{\rightarrow} N$
• $N\overset{+3}{\rightarrow} Q \overset{+1}{\rightarrow} R$
• $R\overset{+2}{\rightarrow} T \overset{+1}{\rightarrow} U$
• ${\color{Magenta} U} \overset{+3}{\rightarrow} {\color{Magenta} X} \overset{+1}{\rightarrow} Z$

So, the correct answer is $(D).$
