[amp_mcq option1=”A” option2=”D” option3=”K” option4=”N” correct=”option1″]
The missing character is K.
The sequence is a simple alternating repetition of the letters A and K. The first letter is A, the second letter is K, the third letter is A, the fourth letter is K, and so on.
The answer is K because it is the next letter in the sequence after A.
