Correct Answer: 1660


Solution : Given:
12, 12, 14, 42, 46, 230, 236, 1652, ?

In the above-given series, multiply and add alternately, the consecutive natural numbers.
12 × 1 = 12; 12 + 2 = 14; 14 × 3 = 42; 42 + 4 = 46; 46 × 5 = 230; 230 + 6 = 236; 236 × 7 = 1652; 1652 + 8 = 1660

So, the missing number is 1660. Hence, the second option is correct.
