Question

if mth term of Ap is n and nth term of an Ap is n find m+n th term​

Answer 1

Step-by-step explanation:

mth term, a+ (m-1)d =n ...i

nth term, a+(n-1)d =m...ii

on sub ,

md -nd =n-m

d =-1

therefore,a= m+n+1

m+n th term ,

a+(m+n-1)d

=m+n+1+(m+n-1)-1

2

a=first term

d =common difference
