Introduction OF Sequence and Series and A.P || Formation OF A.P and General term OF 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.:

1,3,9 can be terms of (A) an A.P. out not of a G.P (B) G.P. but not of an A.P. (C) A.P. and G.P both (D) neither A.P nor G.P

Suppose mth term of an A.P. is 1/n and nth term of the A.P. is 1/m. If rth term of the A.P. is 1, then r is equal to

If sum of first 20 terms of an A.P. is equal to sum of first 30 terms of the A.P. then sum of the first 50 terms of the A.P. is

If 7th term of an A.P. is 9 and 9th term of the A.P. is 7, then 20th term of the A.P. is

Is 5,8,11,14,…….an A.P.? If so then what will be the 100th term? Check whether 92 is in this A.P.? Is number 61 in this A.P.?
