Identify the sequence (If it does not fit any of the 4 sequences, give reasons behind why it doesn�t work)
You only need to check for common difference and common ratio.
13,21,34,55,89,144 ...
Common diff ? 21-13 = 8 but 34-21 = 13 so no common diff.
Common ratio ? 21/13 = 1.615.. and 32/21 = 1.523
So not arithmetic and not geometric
-------------------------------------------
So the same for the following streams of numbers.
