The ratio of the sum used of nth term of 2 Aps is given as

$S_n/(S'_n)=(7n+1)/(4n+27)$

$=(n/2(2*4+(n-1)7))/(n/2(2*31/2+(n-1)4)$

So the ratio of nth term of 2 Aps will be given by

$t_n/(t'_n)=(4+(n-1)7)/(31/2+(n-1)4)=(14n-6)/(8n+23)$

The ratio of the sum used of nth term of 2 Aps is (7n+1):(4n+27),(7n+1):(4n+27),(7n+1):(4n+27), Find the ratio of the nthnthnth term..term..term..?
