    Mathametic functions.

    If function f is f(n) = f(n-1)+f(n-2).

    And f(1) = 3
    f(3) = 10

    What is f(6) ?

    Could some one help me how to solve this problem - thanks.

    \begin{array}{l}<br />
 f(3) = f(2) + f(1) \\ <br />
 10 = f(2) + 3 \\ <br />
 \end{array}
    Now solve for f(2).
    Now apply the rule to find f(6).
