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

${S}_{n} / \left(S {'}_{n}\right) = \frac{7 n + 1}{4 n + 27}$
=(n/2(2*4+(n-1)7))/(n/2(2*31/2+(n-1)4)
${t}_{n} / \left(t {'}_{n}\right) = \frac{4 + \left(n - 1\right) 7}{\frac{31}{2} + \left(n - 1\right) 4} = \frac{14 n - 6}{8 n + 23}$
