Plug n = 1 into the expression 20-9n and we get
20-9n = 20-9*1 = 20-9 = 11
So 11 is the first term of the series that we add up. Therefore the answer must be choice C, which has 11 listed as the first term added
Let x be 1, y=-12
let x be 2, y=-36
let x be 0, y=-4
let x be 3, y =-108
let x be -1, y=-4/3
let x be -2,y=-4/9
While both a and c work the most likely answer that they want would be A because it represent the cents already and it shows all possible ways that those two values can be split among 1 dollar
