What is the last letter in this sequence?
T, H, E, R, A, T, E, N, __
  

Top answer

The only thing I can come up with is if you label the letters with their numerical order in the English alphabet, you get the following sequence of numbers: 20 8 5 18 1 20 5 14 __ , that is, T is the 20th letter in the alphabet, H is the 8th, etc. If you look at this sequence of numbers, you see that it starts with 20, and the 6th number is also 20, and moreover, the two numbers preceding the second 20, 18 and 1, add up to 19, which is one less than 20. Furthermore, the 7th and 8th numbers, 5 and 14, also add up to 19, which again is one less than 20.

  • This seems to provide a strong impetus to name the 9th letter also as 20, since it seems to fit the "pattern" previously established.
  • As further evidence, the second and third numbers, 8 and 5, add up to 13, and the 8th letter is 14, which seems to relate the first half of the sequence to the second half.
