Senior high school mathematics know the ratio of the sum of the first n terms of two arithmetic sequences, how to find the ratio of the general term formula? The sum of the first n terms of the arithmetic sequence {an} and the arithmetic sequence {BN} are TN and Sn respectively, and TN / Sn = 2n / 3N + 1?
T(2n-1)=(2n-1)*a(n)
S(2n-1)=(2n-1)*b(n)
a(n)/b(n)=T(2n-1)/S(2n-1)=2(2n-1)/[3(2n-1)+1]=2(2n-1)/(6n-2)=(2n-1)/(3n-1)
