C Correct answer
Explanation

The pattern is: 1*1+2=3, 3*3+6=15, 15*5+30=105. The multipliers are odd numbers (1, 3, 5, 7) and the added values are multiples of 6 (2, 6, 30, ...). Alternatively, 1*3=3, 3*5=15, 15*7=105, 105*9=945.

AI explanation

The series follows a multiplication pattern where each term is multiplied by consecutive odd integers to get the next term. The calculations are 1 times 3 equals 3, 3 times 5 equals 15, and 15 times 7 equals 105. Continuing this method, 105 multiplied by 9 gives the next term of 945.
