Answer is Right!
Answer is Wrong!
The answer is $\boxed{\text{B}}$.
The sequence is a simple alternating repetition of the numbers 21 and 23, with a 22 inserted after every other 21.
Option A is incorrect because it is the number that comes after 23 in the sequence, but the question asks for the number that comes after 22.
Option C is incorrect because it is the number that comes after 24 in the sequence, but the question asks for the number that comes after 22.
Option D is incorrect because it is not a number in the sequence.
