The correct matches are:
1. {4, 6, 8, 10, ... ] where f(n) = f(n-1) + 2 for n > 1 matches f(n) = 2n + 2
2. {4, 3, 2, 1, ... ] where f(1) = 4 and f(n) = f(n-1) - 1 for n > 1 matches f(n) = 5 - n
3. {-1, 1, 3, 5, ... } where f(1) = -1 and f(n) = f(n-1) + 2 for n > 1 matches f(n) = 2n - 3
4. 1, -2, -3, -4, ... where f(1) = -1 and f(n) = f(n-1) - 1 for n > 1 matches f(n) = -n+1
Match the sequence and recursive expression to its explicit expression. (2 points)
f(n) = ール
f (n) = 2n - 3
f (n) = 2n + 2
J(n)=-7+5
