The Number Puzzler: The Art of Cracking Number Sequence Puzzles

Brilliant number sequences where you have to discover the rule. The book is well organised: initially puzzles that are based on one operation are grouped together, starting with worked through examples and then proceeding to more complex sequences. I have started using it with 8 year olds who are very much enjoying it.

Very good, Starts with the basics and takes you through more complex ones

So poorly written.
