This is the prime numbers:
O = 1
T = 3
F = 5
S = 7
E = 11
T = 13
S = 17
One has been included although not being prime. Two has been left out although prime. The next Prime number after 17 is 19, and so the next letter would be N.
The sequence "0ttffsse" represents the first letters of the numbers: zero (0), one (t), two (t), three (f), four (f), five (s), six (s), and seven (e). The next number in the sequence is eight, which starts with the letter "e." Therefore, the next letter in the sequence is "e."
l
G
When you answer sequence questions, look for a repetition anywhere. We can see that the first letter and the last letter is an 'F' so the sequence must be FHEXFHEXF.... so your answer is F.
The sequence pattern appears to be alternating between a number and its corresponding letter in the alphabet. The numbers 1, 2, 3, 4 correspond to the letters A, B, C, D. Therefore, the next letter in the sequence would be E.
the next letter would be 'b'
f
E
E. Eight.
d
The sequence "0ttffsse" represents the first letters of the numbers: zero (0), one (t), two (t), three (f), four (f), five (s), six (s), and seven (e). The next number in the sequence is eight, which starts with the letter "e." Therefore, the next letter in the sequence is "e."
l
G
The next letter is L. Here is the sequence: a _ _ de _ _ hi _ _ lm.
The next letter in the sequence is T. The sequence follows the alphabetical order, but jumps around by alternating the location of the letters in the alphabet.
When you answer sequence questions, look for a repetition anywhere. We can see that the first letter and the last letter is an 'F' so the sequence must be FHEXFHEXF.... so your answer is F.
N (First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth)
