Pascal's triangle is a triangular array of the binomial coefficients named after Blaise Pascal. To build it, start with a 1 at the top and place numbers below by adding the two numbers directly above. Within the triangle, the first diagonal contains all 1s, the second contains the counting numbers, the third contains the triangular numbers, and the fourth contains the tetrahedral numbers.

3. PASCAL’S TRIANGLE
 In Mathematics, Pascal's triangle is a triangular array of the binomial
coefficients. It is named after Blaise Pascal, a French Mathematician and
Philosopher.
 To build Pascal’s triangle, start with “1” at the top, then continue placing
numbers below it in a triangular pattern.
 In Pascal’s triangle, each number is the numbers directly above it added
together.

4.  The construction of Pascal’s triangle is shown below:

 Diagonals:
 The first diagonal is, of course, just “1”s.
 The next diagonal has the
Counting Numbers (1,2,3,…)
 The third diagonal has the
Triangular Numbers.
 The fourth diagonal has the
Tetrahedral Numbers.
