A puzzle that asks for the pattern (and usually the next term) in a given number sequence.

The pattern is often mathematical, but sometimes is from common knowledge, structures (for example Morse code) or language (for example alphabetical ordering).

For some advice on how to create interesting number sequence puzzles (and what not to do), you can look at this meta question.

Many common "brainteaser" number sequences, such as the "Look and Say" sequence, have already been posted here. If you are sharing a sequence that is not original, please make sure to search for duplicates with at least the first few terms of the sequence.
