Illustration Based upon A.M and Properties OF A.P

Let fourth therm of an arithmetic progression be 6 and m^(th) term be 18. If A.P has intergal terms only then the numbers of such A.P s is "____________"

The sum oif the first ten terms of an A.P. is equal to 155, and the sum of the first two terms of a G.P. is 9. Find these progressionsif the first term of the A.P. equals the common ratio of the G.P. and the 1st term of G.P. equals the common difference of A.P.

(i) The nth term of a progression is 2n+1. Prove that it is an A. P. Also find its 5th term. (ii) The nth term of a progression is linear expansion in 'n' . Show that it is an A.P. (iii) The nth term of a progression is (n^(2)+1) . Show that it is not an A.P.
