The numbers in these logical sequences have been replaced by their initial letter.

For example, the letters T, F, S, E, T, T ... correspond to the sequence of even numbers (2, 4, 6, 8, 10, 12 ...).

Determine the corresponding numbers for these sequences:

1. O T S T F T T T F F

2. T O F T S F E S T N T E

3. F T O S T S E F T O

4. O S E F N T S T F T T E

5. T T F S E T S N T T

6. F T T S F O S T S F T S

1. 1, 3, 6, 10, 15, 21, 36, 45, 55
(+2, +3, +4, +5, ......)

5. 2, 3, 5, 7, 11, 13, 17, 19, 23, 29
(prime numbers)

FWIW I also got the same answer as Popstar Dave for series 2
