Answer 1

Answer:

This is the required C program for the question.

#include <stdio.h>

int main()  {

   int n,i,j,a,b;

   printf("Enter number of rows for the pattern - ");

   scanf("%d",&n);

   for(i=1;i<=n;i++)   {

       a=2,b=3;

       for(j=1;j<=i;j++)   {

           printf("%d ",a);

           a+=b;

           b+=2;

       }

       printf("\n");

   }

   return 0;

}

Explanation:

• At first, I have asked the user to enter the number of rows for the pattern.
• Then, I have created a loop that iterates n times where n is the number of rows.
• Then, another loop is created for displaying the columns. This loop iterates i times where i is the row number (as row number = number of cols on that row).
• Then, I have initialized a = 2, b = 3
• Inside the second loop, value of a is displayed. Value of a is incremented by 2 and value of b is incremented by 3.
• After displaying the row, a new line is displayed.
