A triangular array of numbers made up of the coefficients of the binomial expansion.
Pascal's triangle is an array of numbers that is constructed by beginning with a row of two ones: 1 1. Each new row after the starts and ends with a one, and the other numbers are formed by adding the numbers above and on either side of them: [ DMTA, p. 322, Precalculus and Discrete Mathematics, UCSMP, p. 610
A triangular array of binomial coefficients.
A triangular arrangement of numbers in which each number in any row is the sum of the two numbers immediately above it.
A triangular arrangement of numbers in which each number is the sum of the two numbers above it in the preceding row.
A triangular arrangement of numbers in which each row starts and ends with 1, and each other number is the sum of the two numbers above it. (H) 10 10
In mathematics, Pascal's triangle is a geometric arrangement of the binomial coefficients in a triangle. In the English-speaking world, it is named after Blaise Pascal. In some other languages, it is named after mathematicians who studied it centuries before him.
