Concept

Pascal's Triangle

The Pascal's triangle is a triangular representation of the coefficients in the expansion of a binomial expression. In other words, it contains the coefficients that result when expanding the expression

(a + b)^{n},

with

n = 0, 1, 2, \dots

The rows are numbered from top to bottom starting with $0 .$ The number in each cell equals the sum of the numbers in the two neighboring cells above.
