A Correct answer
Explanation

The pattern is: 2*2+1=5, 5*3+1=16, 16*4+1=65, 65*5+1=326, 326*6+1=1957.

AI explanation

The series follows a pattern where each term is multiplied by an increasing integer and then 1 is added. Multiplying 2 by 2 and adding 1 gives 5, multiplying 5 by 3 and adding 1 gives 16, and multiplying 16 by 4 and adding 1 gives 65. Following this pattern, multiply 326 by 6 and add 1, which is 1956 + 1 = 1957. The result is 1957.
