Here are four more sequence puzzles. The challenge is to guess the pattern and hence fill in the missing terms. Each "???" denotes exactly one missing term.
- 6, ???, 5, 8, 4, ???, 7, 3, 4, ???, 4 (now solved by March Ho)
- Henry, Lily, Ben, Ned, Natalie, ???, Albert, Simon (now solved by KSab)
- 73, 74, 88, 51, 28, 36, 84, 50, 83, 99, ??? (now solved by Len)
- 40, 30, 70, 39, 54, 74, 23, ??? (whoever solves this will get the accepted answer)
Please let me know whether these are too easy, too hard, or neither! I've tried to arrange them in order of difficulty, but I could be completely wrong with this.
Hint (in riddle form):
The same thing coming more than once,
Sometimes coming once a month.
Then the wood on which you eat,
Perhaps excelling at what it does.
