[" 20.If "m" times the "m" th term of an "AP" is equal to "n" times its nth term,find the "(m+n)" th term of the "],[" AP."]

If m times the mth term of an A.P. is equal to n times its nth term, find (m + n) th term of the A.P.:

If m times the mth term of an A.P is equal to n times its nth term then show that (m+n)th term of the A.P is zero .

If m times the mth term of an AP is equal to n times its nth term, then show that (m + n)th term of an AP is zero.

If m times the m^(th) term of an A.P. is equal to n times its n^(th) term, then show that the (m + n)th term of the A.P. is zero.

If m times the m^(th) term of an A.P is equal to n times its n^(th) term, show that the (m + n)^(th) term of the AP is zero.

if m times the mth term of an A.P. is equal to n times the nth term and m!=n show that (m+n) th is zero.

if 9 times the 9 th term of an AP is equal to 13 times the 13 th term , then the 22 nd term of the AP is

if 9 times the 9 th term of an AP is equal to 13 times the 13 th term , then the 22 nd term of the AP is

If m times the m^(th) term of an A.P. is equal to n times its n^(th) term , then show that (m+n)^(th) term of the A.P. is zero .
