This document discusses patterns, iterations, and inductive reasoning. It introduces common iterative patterns like counting up by ones, threes, or fours. It defines iteration as a process that is repeated, and shows an iteration diagram demonstrating how each repetition in the sequence is calculated based on the input and previous output. As an example, it also shows how the value of an item like a moped depreciates by 30% each year in a repeating pattern.

Appreciation/Depreciation Rates
Mr. Dicken's moped (Susan) was
bought brand new for $1,400.
After each year, Susan is only worth 70%
of the previous value.
1400 Brand new
1400 x 70% = 980 After 1st year
After 2nd year
After 3rd year
