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. $\text{PW}$

Answer 1

positional value of alphabets as:

A=1; D=4

C=3; G=7

F=6; K=11

J=10; P=16

1st letter follows 1>3>6>10 (+2+3+4) so next will be +5=10+5=15=O

2nd letter follows 4>7>11>16 (+3+4+5) so next will be +6=16+6=22=V

 

thus, OV (OPTION A)
