Correct Answer: ARMV
Solution :
Given:
ENQR, CPOT, ?, YTKX
Subtract 2 and add 2 alternatively from each letter of the previous term to obtain the next term in the series –
ENQR
→
E
– 2 = C;
N + 2 = P; Q
– 2 = O;
R + 2 = T
CPOT
→
C
– 2 = A;
P + 2 = R; O
– 2 = M;
T + 2 = V
ARMV
→
A
– 2 = Y;
R + 2 = T; M
– 2 = K;
V + 2 = X
So, ARMV is the missing term in the series. Hence, the fourth option is correct.
