​@rishav_anand Use Python. 

n = int(input("Enter a number: "))

for i in range(1, n + 1):
    if i % 2 == 1:  # Odd rows = numbers
        for j in range(1, i + 1):
            print(j, end=" ")
    else:  # Even rows = letters
        for j in range(1, i + 1):
            print(chr(64 + j), end=" ")  # chr(65) is 'A'
    print()  # new line after each row

​@Aaron.Gleason thanks for the code but i want to print this with the help of automation anywhere without using python 

​@rishav_anand Automation Anywhere is not a general programming language. It is a business automation language. As such, Python is a better language for this specific exercise. You can integrate Python directly into Automation Anywhere, and we frequently do for tasks such as yours that are more a programmer exercise than a business automation exercise. It’s a matter of using the right tool for the job.

That being said… it can be done…
