F(1)=4
f(n)=f(n−1)⋅(−0.5)


Find an explicit formula for f(n)f(n)f, left parenthesis, n, right parenthesis.

f(n)=0+2(n−1)

Step-by-step explanation:

From the recursive formula, we can tell that the first term of the sequence is 0 and the common difference is 2.

Note that this solution strategy results in this formula, however an equally correct solution can be written in other equivalent forms as well.
