If S1,S2,S3 are the sum of n, 2n, 3n terms respectively of an A.P. then S3S2−S1
If sum of n, 2n, 3n terms of an A.P. are S1,S2,S3 respectively, then the value of S3S2−S1 is
The sum of n, 2n, 3n terms of an A.P. are S1, S2, S3 respectively. Prove that S3 = 3(S2 – S1).
Let sum of n, 2n, 3n terms of an A.P. be S1, S2 and S3 respectively, show that S3=3(S2−S1)
