Selection of terms in an AP

Question on nth terms in A.P.

The first and last terms of an A.P. are - 7 and 233 and the sum of the A.P. is 9153. Find the number of terms in the A.P.:

Sum of first terms of an A.P. is 9 less than the sum of next 3 terms of the same A.P. and second term is 2 then 4^(th) term of that A.P. is :

In an A.P. sum of three consecutive terms is 27 and their product is 504, find the terms. (Assume that three consecutive terms in A.P. are a -d, a, a+d)

The sum of the first five terms of an A.P. and the sum of the first seven terms of the same A.P. is 167. If the sum of first 10 terms of this A.P. is 235, find the sum of its first twenty terms.

If the sum of p terms of an A.P. is q and the sum of q terms is p , then the sum of the p+q terms will be

The first and the last terms of an A.P. are 17 and 350 respectively. If the common difference is 9, then how terms are there in the A.P. ?
