Complete the following series.
J, Q, L, O, N, ?, P, K
Show answer & explanation
Correct answer: A
Explanation
The given sequence is an alternating series consisting of two independent patterns:
• Odd-positioned terms (+2 pattern):
J (10) + 2 = L (12)
L (12) + 2 = N (14)
N (14) + 2 = P (16)
• Even-positioned terms (−2 pattern):
Q (17) − 2 = O (15)
O (15) − 2 = M (13)
M (13) − 2 = K (11)
Thus, the missing letter is M.
Therefore, the correct option is (A).
