Hi, I am going through some calculus questions and came across this particular question which I don't really understand. It says:
Consider the sum
We haven't spent a great deal of time on summations in lectures, so I was quite confused how to approach this, as isn't the sigma the expression for this sum... Any help would be greatly appreciated.
Sorry, I didn't post the end of the question, it was supposed to say find and expression for this sum. Thats why I am so confused because the sum is 2 + 5 + 8 + 11 + .... + 3n - 1 so isn't the expression of the sum the summation notation? Maybe the original question in the book has a typo in it...

The simplification of this answer is left for you to do.
The research of the formula I used is left for you to do eg. How to Sum the Integers from 1 to N - wikiHow
