    Summation Notation (Sigma) Help

    I understand about summation notation except for one type of problem.
    This may be hard to summarize, but here goes.

    above the Sigma is the number 8, below it is i=2, and to the right of it is the number 4. From the information that I can gather the correct answer would be 32 (8X4). Is this right, or would it be starting at 2 and ending at 8, so then there would be 7 terms, making the answer 28 (7X4). Thanks for the help, this is driving me crazy.

    Hello, kangadm!

    I understand about summation notation except for one type of problem.

    \sum^8_{i=2} 4

    Would it be starting at 2 and ending at 8, so then there would be 7 terms,
    making the answer 28 (7x4)?
    Correct!
