The mth term of a Geometrical Progression is n and nth term is m. Find (m+n)th term.
I've tried this:
Tm = arm-1 = n (Eq 1)
Tn = arn-1 = m (Eq 2)
Subracting 2 from 1
rm - r - rn + r = n-m
rm - rn = n-m
rm + m = rn + n
I don't know how to proceed. I don't even know if I have done this correctly until this point.
