What is Pascal's Triangle? Explain it in detail.

Dear student 

Here is the answer to your query.

 

Pascal’s triangle is as follows,

In the first row, we write only the number 1. Now, to write the numbers in the following rows, add the number directly above and to the left with the number directly above and to the right to find the new value. If either the number to the right or left is not present, replace it by a zero.

 

In the third row, 2 = 1 + 1

In the fourth row, 3 = 1 + 2

In the fifth row, 4 = 1+ 3 and 6 = 3 +3 and so on
