Which of the following letter clusters will replace the question mark (?) in the given series
KI, EK, ZM, VO, SQ, QS,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. PU.
Given series: KI, EK, ZM, VO, SQ, QS,?
The series follows this pattern:
KI, EK
K - 6 = E
I + 2 = K
EK, ZM
E - 5 = Z
K + 2 = M
ZM, VO
Z - 4 = V
M + 2 = O
VO, SQ
V - 3 = S
O + 2 = Q
SQ, QS
S - 2 = Q
Q + 2 = S
QS,?
Q - 2 = P
S + 2 = U
So, the next term in the series is PU.
