    Smile Discrete Maths Homework

    Hi, I'm struggling with the new module in Discrete Maths.
    Here is the question where I'm stuck.

    Write out the first five values of F if
    • F(1) = 1 and for n ≥ 2
    • F (n) = F (n 1) + 2n 1. (8 Marks)
    Can you guess what the actual F (n) will be? (6 Marks)

    Thank you very much..

    F(2)=F(2-1)+2(2)-1=4
    F(3)=F(3-1)+2(3)-1=9
    F(4)=F(4-1)+2(4)-1={\color{red}?}
