Q)
The m th term of an A.P. is n and its nth term is m. Its p th term is:
(a) m +n + P
(b) m +n-p
(c) m-n + P
(d) None of these​

Answer 1

Answer:(b) m+n-p

Step-by-step exprlanation:

d=m-n/n-m

=-1

nth term=m

a+(n-1)d=m

a+(n-1)×-1=m

a-n+1=m

a=m+n-1

therefore pth term

pth term =a+(p-1)d

= m+n-1+(p-1)×-1

=m+n-1-p+1

ie pth term =m+n-p
