1) k is 180*-120*=60*
2)M is 180*-40*=140*
1,4,7,10,13,16,19,22,25,28,31,34,37,40,43,46,49,52,55,58,61,64,67,70,73,76,79,82,85,88,91,94,97,100
f(n) = 1 + 3(n-1) = 1 + 3n - 3 = 3n -2
f(22) = 3(22)-2 = 66-2 = 64
This is the calculator I use to help solve problems I have in math, so it might be helpful, the answer would be -.75 as showed on the calculator/picture above.
