Mathematicians named Pascal’s triangle after the French mathematician Blaise Pascal. Pascal’s triangle is a triangular graph.
In Pascal’s triangle each number is the sum of the two directly above it. The numbers in each row are numbered beginning with 0 for the first row. Each number is positioned either to the left or to the right of the numbers in the rows above. The sum of the elements of a single row is twice the sum of the row preceding it. A Pascal’s triangle can expand infinitely.
