  • Let a,b,c,d and p be any non zero distinct real numbers such that  <img alt="(a^2+b^2+c^2)p^2-2(ab+bc+cd)p+(b^2+c^2+d^2)=0" src="http://entrancecorner.codecogs.com/gif.latex?%28a%5E2&plus;b%5E2&plus;c%5E2%29p%5E2-2%28ab&plus;bc&plu

Let a,b,c,d and p be any non zero distinct real numbers such that  (a^2+b^2+c^2)p^2-2(ab+bc+cd)p+(b^2+c^2+d^2)=0 then
Option: 1 a,c,p are in A.P
Option: 2 a,b,c,d are in A.P
Option: 3 a,b,c,d are in G.P
Option: 4 a,c,p are in G.P

If a, b, c, d are in G P

\\\left(a^{2}+a^{2} r^{2}+a^{2} r^{4}\right) p^{2}-2\left(a^{2} r+a^{2} r^{3}+a^{2} r^{5}\right) p+\left(a^{2} r^{2}+a^{2} r^{4}+a^{2} r^{6}\right)=0\\\Rightarrow p^{2}-2 p r+r^{2}=0\\ \Rightarrow(p-r)^{2}=0

Correct Answer: Option C
