Question

If the sum of n terms and 2 AP are in the ratio 3n + 5 ratio 5n+ 7 then there and nth term are in the ratio

Answer 1

Answer:

In the ratio 3n + 5 : 5n + 7, if you put the value of n as 2n - 1, then you'll get the ratio of nth terms. So this is the answer. So remember this that, if the ratio of sums of two APs are in the ratio an + b : cn + d, then put the value of n as 2k - 1 to find the ratio of kth terms.
