1
Rules Behind Patterns
Every pattern hides a rule. The sequence $2,4,6,8,\ldots$ has rule *add 2*. The sequence $1,2,4,8,\ldots$ has rule *multiply by 2*. Spotting the rule lets us predict the next term.
2
Number Shapes
Numbers can be drawn as dots in shapes. Triangular: $T_n = n(n+1)/2$ . Square: $S_n = n^2$ . Sum of first $n$ odd numbers equals $n^2$ .
3
Fibonacci-like Patterns
Some patterns depend on previous terms. Fibonacci: $1,1,2,3,5,8,13,\ldots$ each term = sum of two before.
4
Patterns in Nature
Patterns appear in flower petals (often 3, 5, 8, 13), pinecones, snail spirals, and honeycombs.
