The row $9$ of Pascal’s triangle is $\text{1}93684126843691$ .

Explanation of Solution

Given information:

The given Row $8$ of Pascal’s triangle

  $1,8,28,56,70,56,28,8,1$

Calculation:

The given Row $8$ of Pascal’s triangle

  $1,8,28,56,70,56,28,8,1$

The first and last elements of the Pascal’s triangle are $1$ and each other element is a sum of two element sum of two element which is right above it.

  $\text{Row8:}\text{1}\text{8}\text{28}\text{56}\text{70}\text{28}\text{8}\text{1}$

To find the $\text{Row9}$ ,

  $\text{Here}9=1+8,36=8+24,84=28+56$

  $\text{Row9:}\text{1}93684126843691$
