Which letter cluster will replace the question mark (?) to complete the given series?
SPIN, RQJM, ?, PSLK, OTMJ
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. QRKL.
Given series: SPIN, RQJM, ?, PSLK, OTMJ
S - 1 = R; R - 1 = Q; Q - 1 = P; P - 1 = O
P + 1 = Q; Q + 1 = R; R + 1 = S; S + 1 = T
I + 1 = J; J + 1 = K; K + 1 = L; L + 1 = M
N - 1 = M; M - 1 = L; L - 1 = K; K - 1 = J
