Solve Maths Sequences & Series - Get Passing Grade Now

In summary, the conversation is about someone asking for help with the last 5 questions in their math assignment. The questions involve finding the possible values for n and the nth partial sum, as well as solving a geometric ratio and an arithmetic problem. The person speaking is concerned that if the individual asking for help does not understand these concepts, they should not pass maths.

Do you mean to say you can't do 2 and 4?? What are the possible values for n? Do you know what an nth partial sum is?

Hint: 3 is a geometric ratio. What is the sum for this?

If, as you appear to be saying, you know nothing at all about these problems, why should you pass maths?

The second problem asks you to find \(\displaystyle \sum_{n=0}^4 (n-1)^2\). Do you know what that means? If you do then this is a simple arithmetic problem. If you do not then you should Not pass maths!
