(#M40007613) ELITMUS QUESTION Keep an EYE

Let Sn denote the sum of first n terms of an A.P.. If S2n = 3Sn, then the ratio S3n/Sn is equal to
(a) 4 (b) 6
(c) 8 (d) 10

Solution

We know that Sn = n(n+1)/2
now it is given that
S2n = 3Sn
=> 2n(2n+1)/2 = 3n(n+1)/2
=> 2(2n+1) = 3(n+1)
=> 4n+2 = 3n+3
=> n = 1
then S3n/Sn = [3n(3n+1)/2]/[n(n+1)/2] = 3*4/1*2 = 6
