### Theory:

Pascal's triangle is created by the French mathematician Blaise Pascal.

The following triangle of numbers is the Pascal's triangle.

Construction of Pascal's triangle:
1. Start with $$1$$ on the top and with $$1$$’s running down the two sides of a triangle.

2. From the third row, each new number lies between two $$1$$'s is the sum of the above two numbers.

3. This triangle goes down infinitely.
