This is pretty simple. If you are stuck, then you should talk to classmates or your teacher. Google is a very good place to look. We are not going to do your homework for you.

For now, your best is nothing.
Show your code, at least we will know you don't just want a full blowup solution.

I am sorry, but this is "Coding 101" level, you need to reread your lessons.
Come back if you have a specific problem once you have some code.

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.

As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.

Hello,

I'm not going to write it for you but here are a few clues.
First you need to ask for the number, using Java it could be something like

Scanner (Java Platform SE 8 )[^]

Google a bit and you should find how to do it. There are many ways to do it, this is just an example.

Secondly you need to loop from 1 to the number entered. This is achieved using a loop.

The for Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)[^]

Thirdly you need to calculate the values requested, it's just a series of additions in the loop and a division after the loop.
Java Basic Operators[^]

lastly display the results.
Java Output[^]

Google is your friend. There are countless learning resources.
