The nth term and sum of the first n terms of AP.
Find the sum of first 25 terms of the A.P.
Find the sum of first 25 terms of the A.P. whose nth term is given by an = 5 + 6n. Also, find the ratio of 20th term to 45th term.

In an A.P, if $ S_{n} = 3n^2 + 5n $ and $ a_k = 164 $, find the value of k
The sum of four consecutive numbers in an AP is 32 and the ratio of the product of the first and the last term to the product of two middle terms
The sum of four consecutive numbers in an AP is 32 and the ratio of the product of the first and the last term to the product of two middle terms
...In an AP, if the common difference (d) = -4, and the seventh term
In an AP, if the common difference (d) = -4, and the seventh term (a7) is 4, then find the first term.
If the ratio of the sum of the first n terms of two A.Ps is (7n + 1) : (4n + 27)
If the ratio of the sum of the first n terms of two A.Ps is (7n + 1) : (4n + 27), then find the ratio of their 9th terms.
