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."
G
l
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 "fstffs" appears to follow a pattern of alternating letters with a repeated "f" and "s." The next letter in the sequence is likely to be "t," continuing the pattern of alternating "f" and "s" with the addition of "t" at the beginning. Therefore, the next letter is "t."
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)
