Correct Answer: 23
Solution : Given: 15, 17, ?, 33, 47, 65
Multiply odd numbers, starting from 1, by 2, and then add the resultant to the previous numbers to get the next numbers of the series. 15 + (2 × 1) = 15 + 2 = 17; 17 + (2 × 3) = 17 + 6 = 23; 23 + (2 × 5) = 23 + 10 = 33; 33 + (2 × 7) = 33 + 14 = 47; 47 + (2 × 9) = 47 + 18 = 65
So, 23 is the missing number of the series. Hence, the fourth option is correct.
