If a, b, c, d are distinct integers in A. P. Such that `d=a^2+b^2+c^2`, then a + b + c + d is

If a,b,c,d are distinct integers in A.Puch that d=a^(2)+b^(2)+c^(2), then a+b+c+d is

If a,b,c,d are distinct integers in an A.P. such that d=a^(2)+b^(2)+c^(2), then find the value of a+b+c+d

If a,b,c,d are four distinct positive numbers in G.P.then show that a+d>b+c.

Let a, b, c, d be distinct integers such that the equation (x - a) (x -b) (x -c)(x-d) - 9 = 0 has an integer root 'r', then the value of a +b+c+d - 4r is equal to :

if a,b,c and d are distinct integers such that a+b+c+d=17, then the real roots of (x-a)(x-b)(x-c)(x-d)=4 are

if a,b, c, d and p are distinct real number such that (a^(2) + b^(2) + c^(2))p^(2) - 2p (ab + bc + cd) + (b^(2) + c^(2) + d^(2)) lt 0 then a, b, c, d are in
