[" 1.Sum of the first "p,q,r" terms of an A.P "a,b,c" are respectively."],[" Prove that "(a)/(p)(q-r)+(b)/(q)(r-p)+(c)/(r)(p-q)=0]

The sums of first p, q, r terms of an A.P. are a, b, c respectively. Prove that (a)/(p) (q-r) +(b)/(q) (r-p) +(c )/(r) (p-q) =0

Sum of the first p,q and r terms of an A.P are a,b and c,respectively.Prove that quad (a)/(p)(q-r)+(b)/(q)(r-p)+(c)/(r)(p-q)=0

The sum of the first p,q,r terms of an A.P.are a,b,c respectively.Show that (a)/(p)(q-r)+(b)/(q)(r-p)+(c)/(r)(p-q)=0

Sum of the first p,q and r terms of an A.P. are a, b and c, respectively. Prove that, (a)/(p) (q-r) + (b)/(q) (r-p) + (c )/(r ) (p-q) = 0
