1.	If a,b,c,d are four distinct real numbers which are in an A.P., then the smallest positive value of k satisfying 2(a−b)+k(b−c)2+(c−a)3=2(a−d)+(b−d)2+(c−d)3 is
Answer» If $a, b, c, d$ are four distinct real numbers which are in an A.P., then the smallest positive value of $k$ satisfying $2 (a - b) + k (b - c)^{2} + (c - a)^{3} = 2 (a - d) + (b - d)^{2} + (c - d)^{3}$ is
