Generate a Progressive Number Pattern in Python

Program Overview

This Python program prints a structured number pattern where each row starts with a number and grows by adding that number repeatedly.
The first row starts with 1 and prints 3 values: 1, 2, 4.
Subsequent rows follow a pattern where the row number is multiplied by increasing integers.
The final row reaches up to 10 × 10 = 100.

Python Code:

# Generate progressive number pattern
for i in range(1, 11):
    for j in range(1, i + 1):
        print(i * j, end="\t")
    print()

Sample Output:

1
2   4
3   6   9
4   8   12  16
5   10  15  20  25
...
10  20  30  ... 100

Step-by-Step Explanation:

- The outer loop for i in range(1, 11) controls the row number
- The inner loop for j in range(1, i + 1) prints i × j for each column
- end="\t" ensures horizontal spacing between numbers
- print() after the inner loop moves to the next line
