• A. 9, 42
• B. 16, 35
• C. 35, 16
• D. 16, 36

Answer 1

The correct option is C 35, 16

The given series: $14,1,21,4,28,9,?,?$ consists of two series.

1st series: $14,21,28,?$ 2nd series: $1,4,9,?$

in the 1st series, each of the next number is 7 more than its previous number.

In the 2nd series, each of the number is square of natural number starting from 1, 2, 3....

Clearly, $28+7=35$ and $4^2=16$

Hence, option (C) is the correct answer.
