If 29th term of an A.P is twice its 19th term, then the 9th term is

The 29^(th) term of an A.P is twice its 19^(th) term. Its 9^(th) term is equal to

The 24th term of an A.P. is twice its 10th term. Show that its 72th term is 4 times its 15th term.

The 24th term of an AP is twice its 10th term. Show that its 72nd term is 4 times its 15th term.

The 14th term of an A.P. is twice its 8th term. If its 6th term is -8, then find the sum of its first 20 terms.

The 24th term of an A.P. is twice its 10th term. Show that its 72nd term is four times its 15th term.

If (p + 1)th term of an A.P. is twice the (q + 1)th term, then prove that (3p + 1) th term will be twice the (p + q + 1)th term.

If (m+1)th term of an A.P. is twice the (n+1)th term, then prove that (3m+1)th term is twice the (m+n+1)th term

If the 9th term of an A.P is zero then show that the 29th term is twice the 19th term.

The 19th term of an AP is equal to 3 times its 6th term. If its 9th term is 19, find the AP.
