Pascal's triangle has many properties and contains many patterns of numbers.
- The sum of the elements of row n is equal to 2n.
- It is equal to the sum of the top sequences.
- The 1st line = only 1's.
The 2nd line = the natural numbers in order.
The 3rd line = the triangular numbers in order.
The 4th line = the tetrahedral numbers in order.
- Fibonacci numbers
