How to form rows of Pascal triangle

Explanation of Solution

Given: Explain in your own words, explain how to form the rows of Pascal’s triangle .

We can form the consecutive rows of the Pascal’s triangle as :

In the first row, we will write 1 at the top

In the next row , we will write two 1’s . Every row contains a 1 at the start and the end.

In the third row , we will start with 1 , forming the middle term by the summation of the above two terms and finally add a 1.

That means The first and the last t number in each row is 1 .Every other number in each row is formed by adding the two numbers immediately above the number
