1.If a,b,c,da, b, c, da,b,c,d are distinct real numbers such that (a2+b2+c2)p2−2p(ab+bc+cd)+(b2+c2+d2)≤0(a^2+b^2+c^2)p^2 - 2p(ab+bc+cd) + (b^2+c^2+d^2) \le 0(a2+b2+c2)p2−2p(ab+bc+cd)+(b2+c2+d2)≤0, thena.a,b,c,da, b, c, da,b,c,d are in A.P.b.ab=cdab = cdab=cdc.ac=bdac = bdac=bdd.a,b,c,da, b, c, da,b,c,d are in G.P.Login to continueOnly logged in users canattempt or see the solution.
