The pascal triangle:
There are some patterns
Diagonal 1 - Ones
Diagonal 2 - Natural Numbers
Diagonal 3 Triangular Numbers
You can form a equilateral triangle with these numbers.
Add to the base each time
1,3,6, and so on.
You cannot make a triangle with 2 boxes, but you can with 3.
Diagonal 4 3D Tetrahedral/3D pyramids
You can make 3d pyramids(tetrahedral) with these boxes
And it goes so on, the fourth dimension for the 5th row.
Exponentials of 2
The sum of each row equates to a power of 2
row 0 sum is 2^0, row 1 sum is 2^1.
so the sum is 2
