If the nth term of a progression is (4n-10) show that it is an AP. Find its (i) first term, (ii) common difference, and (iii) 16th term.

lf the nth term of an AP is (5n-2), find its (i) first term, (ii) common difference and (iii) 19th term.

The nth term of a progression is 2n+3. Show that it is an A.P. Also find is 10th term.

The nth term of a progression is 2n+3. Show that it is an A.P. Also find is 10th term.

Find the common difference if n^(th) term of AP is 7-4n.

Each term of an A.P. is doubled. Is the resulting sequence also an A.P.? If it is, write its first term, common difference and n^(th) term.
