PASCALTRIANGLE (Levels)

• is the level number of the Pascal Triangle.
• PASCALTRIANGLE(), is a triangle of numbers in which a row represents the coefficients of the binomial series.

## Description

• This function gives the Coefficients of the Pascal triangle.
• In , is the level number of the Pascal triangle.
• Pascal triangle is the arrangement of numbers of the Binomial coefficients in a triangular shape.
• It is started with the number at the top in the 1st row.
• Then from the 2nd row each number in the triangle is the sum of the two directly above it.
• The construction is related to the Binomial Coefficients by Pascal's rule is :

. where is the binomial coefficient.

• This function will return the result as error when .
