Consider the numbers 9 17 21 45 51 65 85 93 153 and 219 and say which of the following words has the most obvious link with them.
Morning, Noon, Afternoon, Evening, Night or Midnight?
I think its "Evening" This is how I came up with that conclusion. Assign the alphabet in order numbers 1 to 26. now start with with the "E" count up to the "V" it's 17. Now continue counting from the "V" to the "E" it's 9. Now count fron the "E" to the "N" it's 9. Continue doing this and all of them will be odd number answers just like your clue numbers. Hope this helps.
