C Correct answer
Explanation

The pattern is: 5*2+1=11, 11*2+1=23, 23*2+1=47, 47*2+1=95, 95*2+1=191. The term 192 is incorrect; it should be 191.

AI explanation

The series follows a pattern where each term is multiplied by 2 and then 1 is added to find the next term. Following this rule, 5 multiplied by 2 plus 1 is 11, 11 multiplied by 2 plus 1 is 23, and 47 multiplied by 2 plus 1 is 95. When we apply this to 95, we get 95 multiplied by 2 plus 1 which is 191, proving that 192 is the wrong number.
