Can you fill in the missing letters in the below sequence?


I have tried planets, periodic table, compass points, dates, months, days etc...

Please help!

I have been told by an administrator to say where this question came from, therefore it came from a quiz my girlfriend did at her University but was never given answers to.

  • $\begingroup$ Do you have any other context clues to go off of? Like what type of class was it? Something that could give more background as to why you think it is a representative sequence instead of a word. $\endgroup$ – likwidfire2k Apr 30 '19 at 20:13

The only English word (that I could find) which fits the pattern is a rather uncommon one:

    $\begingroup$ That seems like a word that would be applicable only in a narrow range of situations. Perhaps only in one part of a narrow range of situations. $\endgroup$ – Gareth McCaughan Apr 30 '19 at 14:23
  • $\begingroup$ I think the letters are more likely to represent words in a sequences (i.e. F,S,S,M,T,W,T being days of the week). $\endgroup$ – chall245 Apr 30 '19 at 15:25

Possible answer

s, y, s, n, r, s, h, e


Order the eight planets by their eccentricity

Mercury 0.2056
Mars 0.0934
Saturn 0.0565
Jupiter 0.0489
Uranus 0.0464
Earth 0.0167
Neptune 0.0095
Venus 0.0068

Take the last letters of each entry to get the sequence y, s, n, r, s, h, e, s

Rotate this sequence by one space to get s, y, s, n, r, s, h, e

  • $\begingroup$ I needed Earth for the h, though. Is there a different approach you were considering? $\endgroup$ – hexomino May 1 '19 at 9:33
  • $\begingroup$ Ah, whoops. I misread -- my bad! $\endgroup$ – Deusovi May 1 '19 at 9:46

    $\begingroup$ (Specifically, I thought the bolded letters were the fixed ones, not the ones you were filling in.) $\endgroup$ – Deusovi May 1 '19 at 9:47
