InterviewSolution

1.	The first term and the mth term of a geometric progression are `a and n` respectively and its nth term is `m`. Then its `(m+1-n)`th term is _____.A. `(ma)/(n)`B. `(na)/(m)`C. `mna`D. `(mn)/(a)`
Answer» Correct Answer - B (i) Use the formula to find `n`th term of a GP. (ii) `ar^(m-1) = n,ar^(n-1) =m`. (iii) `(m+1 -n)`th term =`ar^(m-n)`
