GATE CSE 2012 | Question: 65

Question

Given the sequence of terms, $\text{AD CG FK JP}$, the next term is

• A. $\text{OV}$
• B. $\text{OW}$
• C. $\text{PV}$
• D. $\text{PW}$

Comments

A _______ D , C _____G , F _______ K , J _________P

      FIRST DIFFERENCE IS A -D IN B/W BC DIFFERENCE and this difference is increasing by 1 everytime

 SECOND DIFFERENCE B/W FIRST AND SECOND A -----C IS B and this difference by 1 everytime

A_____D – difference of BC

C ____ G – difference of DEF

F_____K – difference of  GHIJ

J _____P – difference   of KLMNO

O_____V – difference of PQRSTU

SO, the answer is (a) OV

Answer 1

A. $\text{OV}$

• $\text{AD}$ - difference $2\; \text{(B,C)}$
• $\text{CG}$ - difference $3\; \text{(D,E,F)}$
• $\text{FK}$ - difference $4$ and $\text{JP}$ - difference $5$

So, next term will have $6$ difference

Again, each term starts with preceding term's second last letter.

So, $\text{JKLMNOP}:$ next term will start with $O$ and having $6$ difference; it will be $\text{OV}$

Answer 2

A +1 C +2  F+3   J+4  O

D +2  G+3 K +4 P +5 V

ANS IS OV

Answer 3

(A) OV

Explanation-(1) Difference between first character is increasing 2,3,4 then next will be 5.

                 (2) Diffirence between sencond character in increasing by 3,4,5,6 then next will be 7.

 

so the result we got OV which make same difference as above.

Answer 4

A: OV
