COMB, GIUR, KCCH, OWKX, ?
Option 1: SRQM
Option 2: MNQR
Option 3: SQSN
Option 4: SMRQ
Correct Answer: SQSN
Solution :
Given:
COMB, GIUR, KCCH, OWKX, ?
Add 4 and 8 to the positional value of the first and the third letters and subtract 6 and 10 from the positional value of the second and the fourth letters of the previous term to obtain the next term in the series –
COMB
→
C + 4 = G; O – 6 = I; M + 8 = U; B – 10 = R
GIUR
→
G + 4 = K; I – 6 = C; U + 8 = C; R – 10 = H
KCCH
→
K + 4 = O; C – 6 = W; C + 8 = K; H – 10 = X
OWKX
→
O + 4 = S; W – 6 = Q; K + 8 = S; X – 10 = N
So, SQSN is the missing term in the series. Hence, the third option is correct.
