Correct Answer: 105
Solution : Given: 25, 42, 61, 82, ?, 130
In the above-given series, subtract consecutive odd numbers from the previous number to obtain the next number. 25 + 17 = 42; 42 + 19 = 61; 61 + 21 = 82; 82 + 23 = 105; 105 + 25 = 130
So, 105 is the missing number of the series. Hence, the second option is correct.
