what comes next?

O,T,T,F,F,S,S,E,......

Hint: The answer is not "E".

Here is another one:

J,F,M,A,M,J,J,A,.....

To determine what comes next in the sequence: O, T, T, F, F, S, S, E, ......, we need to look for any patterns or relationships among the given letters.

The given sequence appears to be formed by the first letter of each day of the week:

O represents "Monday"
T represents "Tuesday"
F represents "Wednesday"
F represents "Thursday"
S represents "Friday"
S represents "Saturday"
E represents "Sunday"

According to this pattern, the next letter in the sequence should represent the first letter of the day that follows Sunday, which is "M" for "Monday."

Therefore, the answer is M.

Hint: calendar

Those are the first letters of the first 8 numerals.
