The pattern is 2n-3, where n is the number of the term. therefore, a38 of the sequence would be 2(38)-3, or 73.
Basically u do 5÷2=2 1/2
so each person gets 2 slices with 1/2 left
33.51 X 85% (0.85) = 28.48
You find the x coordinates using x = -b/2a = -6/2(-1) = 3
Substitute 3 in the equation and find y
y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3
Vertex (3,-3)
