A sequence is defined by the recursive function f of open paren n plus 1 close paren is equal to negative 10 f n If f of 1 is equal to 1 , what is f of 3 ?
Answer
A
negative 30
B
100
C
negative 1,000
D
3
Explanation
The rule multiplies each term by −10. Starting with f(1) = 1, we get f(2) = −10 and then f(3) = (−10)(−10) = 100, so the answer is B, 100.
