Given that and
We need to determine the value of f(4)
To determine the value of f(4), we need to know the values of the previous terms f(2), f(3).
<u>The value of f(2):</u>
The value of f(2) can be determined by substituting n = 2 in the function
Thus, we get;
Thus, the value of f(2) is 2.
<u>The value of f(3):</u>
The value of f(3) can be determined by substituting n = 3 in the function
Thus, we get;
Thus, the value of f(3) is 1.
<u>The value of f(4):</u>
The value of f(4) can be determined by substituting n = 4 in the function
Thus, we get;
Thus, the value of f(4) is -3.
