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

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

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

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

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