Sequencing the Stone...Logic puzzles require you to think. You will have to be logical in your reasoning.
A group of stones are all lined up. Upon closer inspection, you realize there are numbers on the stones, as follows:
1 - 2 - 3 - 5 - 9 - 12
The last stone has had its number worn off by wind and time, what should the number on the stone read?
HintThis is a logical sequence, not necessarily a mathematical one.
one - two - three - five - nine - twelve - twenty-one
The words for the numbers end in vowels.
