Checking expression in a table

I have been looking through some old posts and what I’m seeing is not helping. Well, it is helpful, but I’m not getting the results :slight_smile:

I have a table where the students type an expression for a sequence in the third line. I’d like to give them a check when they have an appropriate expression. I am trying to use simpleFunction and evaluateAt, but I am clearly not doing it correctly. Can anyone help?

I looked at other examples and used what they did to update your code. I noticed that you didn’t have the , n on the second evaluate part either. This is what I came up with.

Thank you! I have a lot to learn!

I have a lot to learn too. I did not know the answer when I first saw your post. Sometimes I look at problems like this and try to find the answers just to learn new things. Solving questions like this is more fun than grading papers. :slight_smile: :wink:
