The first fourteen letters are repeated except for the seventh and fourteenth. The repeated twelve letters are then repeated except for the sixth and twelfth. The repeated ten letters are then presumably repeated except for the fifth and tenth. Whilst that's not the entire pattern, it's enough to indicate the required letter is K.

I don't understand your question. Was it intended to be treated as a hint?
