    Express in the form a+ib:

    (i+1)(i+2)(i+3)..(i+n)


    I can handle problems like i^n, but this one has been giving me issues.

    The problem is looking for a general expression for the result as a function of n. Multiply the first two terms and simplify the result. Then multiply that by the next term and simplify. Then multiply in the next term... Is there a pattern?
