Explain how to construct Pascal'sTriangle

Question

Use at least 3 sentences.

Answer 1

To construct Pascal's Triangle, start with a single "1" at the top, which represents the zeroth row. Each subsequent row is created by placing "1"s at both ends, with each interior number being the sum of the two numbers directly above it from the previous row. For example, the third row has the numbers 1, 2, and 1 because the "2" is the sum of the two "1"s above it in the second row. This pattern continues infinitely, with each row corresponding to the coefficients of the binomial expansion (a + b)^n, where n is the row number.
