Patterns Within the Triangle


 

Diagonals

The first diagonal is, of course, just "1"s, and the next diagonal has the Counting Numbers (1,2,3, etc).
The third diagonal has the triangular numbers
(The fourth diagonal, not highlighted, has the tetrahedral numbers.)

Odds and Evens

If you color the Odd and Even numbers, you end up with a pattern the same as the Sierpinski Triangle
 
 

Horizontal Sums

What do you notice about the horizontal sums?
Is there a pattern? Isn't it amazing! It doubles each time (powers of 2).

 

Exponents of 11 ⇒ Pascal's Triangle

But what happens with 115 ? Simple! The digits just overlap, like this:
The same thing happens with 116 and so on.
 
 

Fibonacci Sequence

Try this: make a pattern by going up and then along, then add up the squares (as illustrated) ... you will get the Fibonacci Sequence.

(The Fibonacci Sequence starts "1, 1" and then continues by adding the two previous numbers, for example 3+5=8, then 5+8=13, etc)

Pascal's Triangle Symmetry  

Symmetrical

And the triangle is also symmetrical. The numbers on the left side have identical matching numbers on the right side, like a mirror image.
