The question is stated wrong.It should be: "What is the next letter in the series O T T F F ?", and the answer is " S ".These are the initial letters of the words: One Two Three Four Five, followed by Six.
d
It looks as if every third letter is an "r"; the remaining letters are in sequence.
E. They are the initial letters of the numbers 0-7 in words: Zero, One, Two, Seven The next is 8 - Eight
oNe, tWo, tHree, fOur,fIve,sIx etc. It is the second letter of each consecutive number
It is w.
The sequence is the 1st letter, then the 26th letter. Then the 2nd letter, then the 25th letter. Then the 3rd letter, then the 24th letter, and so on. Therefore, D corresponds to W. The answer is W.
The series CYGTNLIT appears to be a simple pattern where each letter is the next letter in the alphabet from the previous letter. Therefore, the next letter in the series would be M.
