Which number will replace the question mark (?) in the following series? 3, 3, 11, 19, 59, ?
Correct Answer: 115
Subject: History
Explanation: This is an alternating series.
For odd positions: 3 (+8) = 11, 11 (+48) = 59.
For even positions: 3 (+16) = 19, 19 (+96) = 115. Thus, the missing number is 115.
