B Correct answer
Explanation

The pattern is: 3*2+2=8, 8*3+3=27, 27*4+4=112, 112*5+5=565. The term 560 is incorrect; it should be 565.

AI explanation

The series follows a multiplication and addition pattern. Multiplying by 1 and adding 5 gives 8, multiplying by 3 and adding 3 gives 27, and multiplying by 4 and adding 4 gives 112. Multiplying 112 by 5 gives 560, but adding 5 should give 565, making 560 the wrong number; the next step would be 565 multiplied by 6 plus 6. The incorrect number is 560.
