Find the common difference for the given sequence. Type a numerical answer in the space provided. 1/4,3/8,1/2,...

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0 

Ifigured it out from watching a khan academy video , i am so sorry about the first answer. but i agree that x= 72. and now you can give the other person brainliest if you want.
