Complete the series.
1, 4, 2, 8, 3, 12, 4, ?
Show answer & explanation
Correct answer: A
Explanation
Series: 1, 4, 2, 8, 3, 12, 4, ?
Separate into two sequences
Odd positions: 1, 2, 3, 4 → increasing by 1 each time.
Even positions: 4, 8, 12, ? → increasing by 4 each time.
So, missing term is: 12+4=16
The correct answer is option 1.
