Choose the correct alternative from the given ones that will complete the series:
4, 1, 16, 4, 36, 9, ?, 16

Show answer & explanation

Correct answer: A

Explanation

Series: 4, 1, 16, 4, 36, 9, ?, 16

Separate into two sequences:

Odd positions:

4, 16, 36, ?

→ 22, 42, 62

So, next term is:

82 = 64

Even positions:

1, 4, 9, 16

→ 12, 22, 32, 42

Hence, the correct answer is option 1.
