Explanation / Answer

Implemented code in java, as no programming language is specified. Please comment if you want it in some other language.

code:

========

import java.util.Scanner;

public class Traingles {

public static void main(String[] args) {

System.out.println("How many triangles: ");

Scanner sc = new Scanner(System.in);

int inp = sc.nextInt(), hi;

for(int i=0; i<inp; i++) {

System.out.println("The height of the triangle: ");

hi = sc.nextInt();

triangle(hi);

}

System.out.println("Process finished with exit code 0");

}

public static void triangle(int h) {

int nums = 1;

for(int i=h; i>0; i--) {

for(int j=1;j<=i ; j++) {

System.out.print(nums +" ");

nums = nums+2;

}

System.out.println();

}

}

}
