    Verifying identities

    I have to verify this identity. It's supposed to be in sigma notation but I don't know how to format it like that. Hope you guys understand what this is trying to say:


    sum from {i = 1} to{n} (2i-1) = n^2 for n = 4,5,6

    Substitute 4 for n in the above and evaluate both sides, are they equal? then you have verified it for n=4.

    Repeat for n=5 and n=6

    Now I have to use rules and formulas to prove that it is equal to n^2 for all natural numbers. How should I approach this?
